Trá»Ânh Kiá»Âm (1503âÂÂ1570) posthumously titled Thế Tá» Minh Khang Thái Vðáng (ä¸Âç¥ÂæÂÂ康太çÂÂ), was an influential political and military figure of ÃÂại Viá»Ât during the Southern and Northern Dynasties period. In name, he served as a supporter of the Revival Lê dynasty emperors, but in reality, he was the actual leader of the Southern Dynasty from 1545 onwards. Though his highest title during his lifetime was Thái Quá»Âc Công (Grand Duke of the State), he is often regarded as the first Chúa (Lord) of the Trá»Ânh family. He established his family as hereditary governors of Vietnam, ruling in the name of the figurehead Later Lê emperors.
Trá»Ânh Kiá»Âm was born into a poor family in Vénh Lá»Âc now known as modern day Thanh Hoa. During his youth, he witnessed the Mạc Dynasty usurp the Lê throne, leading him to join Grand Duke Nguyá» n Kim who was raising an army and war against the Mạc, supporting Lê Trang Tông as emperor. Recognizing Trá»Ânh Kiá»ÂmâÂÂs exceptional prowess and strategic abilities, Nguyá» n Kim married his daughter, Nguyá» n Thá» Ngá»Âc Bảo, to him, entrusted him with military command, and promoted him to the title Dá»±c Nghéa Hầu (Marquis). Trá»Ânh Kiá»Âm achieved numerous victories against the Mạc forces. Which led the Emperor Lê Trang Tông himself trusting him greatly, promoting him to ÃÂại tðá»Âng quân (Grand General) with the noble title Dá»±c QuáºÂn Công (Grand Duke), in 1539 when he was 37 years old.
After his father-in-law Nguyá» n KimâÂÂs death in 1545, Trá»Ânh Kiá»Âm took over leadership of the government and military of the Lê Dynasty until his death, serving under three Lê emperors: Lê Trang Tông, Lê Trung Tông, and Lê Anh Tông. He played a major role in organizing the Southern DynastyâÂÂs government through key decisions such as establishing his headquarters in Vạn Lại, holding civil service examinations in Confucian studies, strengthening the military, recruiting individuals based on talent and merit rather than bureaucrats, repelling Mạc invasions in Thanh Hoa and Nghá» An–, reclaiming ThuáºÂn Hóa and Quảng Nam from Mạc control, and launching major northern campaigns. Although he did not achieve a decisive victory over the Mạc in his lifetime, Trá»Ânh Kiá»Âm laid the foundation for his descendants to complete the restoration of the Lê Dynasty, reclaim ÃÂông Kinh (modern-day Hanoi), and establish the long-lasting Lê-Trá»Ânh era in Vietnamese medieval history. Although he was the de facto ruler of Vietnam, he never assumed a higher position for himself. When he died, his son Trá»Ânh Tùng declared himself a lord and conferred this title posthumously upon his dead father.
Trá»Ânh Kiá»ÂmâÂÂs childhood name was Trá»Ânh Phiến (éÂÂðª¤), later changed to Kiá»Âm. He was born on September 14, 1503 to Trá»Ânh Lâu, and Hoàng Thá» Ngá»Âc Dá»Âc, during the Cảnh Thá»Âng era of Emperor Lê Hiến Tông. He was the third of seven siblings, with four brothers and two sisters. Trá»Ânh Khả, his great-grandfather was a regent during the reign of child-king Lê Nhân Tông, and was a close ally to Lê Lợi considered to be one of VietnamâÂÂs greatest heroes. His birthplace was his motherâÂÂs birthplace the village of Há»Â, in Vá» Quá»Âc commune, Yên ÃÂá»Ânh district, Thanh Hoa province. It was said that when he was born, a red light filled the entire room, astonishing the entire village. From a young age, he was known to be intelligent and stood out from others.
When Kiá»Âm was six years old, his father, the family's breadwinner died. This caused his family's financial and social status to deteriorate, and they faced disdain and discrimination from other villagers. As a result, he and his mother had to relocate to the village of Sóc Sán. To survive, Kiá»Âm worked as a buffalo herder in the Lá» Sán mountains at a young age. While tending buffalos, he often gathered groups of other village children, where at times due to poverty and hunger they stole chickens and ducks for food. They often played war gamesâÂÂsplitting into teams, using the buffalo as war elephants and horses, reeds as banners, practiced fighting armed with knives and salt pots, and organizing different battle formations.
One day he came across a injured buffalo in a nearby area; knowing it was going to die eventually, he killed and cooked it to treat his friends. A villager gathering firewood came across the scene and confronted them. All the children fled except for Kiá»Âm, who remained seated where he was. When questioned, he calmly replied:
The villagers then accused him of theft, dragged him to the village hall for punishment, where many debated whether to drown him to death in the river or report him to the officials. Ultimately, the village chief decided to expel him and his mother from returning. After being expelled, Kiá»Âm moved to Bá» Xuyên village in Yên Mô district.
At the age of 24 (1526), he married a woman from the Trần family, whose name is recorded as Ngá»Âc Lénh. He lived with her in Bá» Xuyên, but historical records do not provide further details about her fate.
In 1527, Dai Viet was in chaos. The ruling Lê dynasty had been overthrown by Mạc ÃÂÃÂng Dung, a former general who seized the throne. Many loyalists of the Lê dynasty refused to accept this change and fled to organise resistance movements. Among them was Nguyá» n Kim, a powerful noble who retreated to the remote region of Cá» Là ©ng (modern-day Cẩm Thá»§y District) to plan an uprising against the Mạc, and advanced his troops. During this time, a Mạc general named Ninh Bang Hầu established his base in Vénh Ninh (Modern day Vénh Lá»Âc). His army controlled the surrounding regions, ensuring they retain their loyalty to the new Mạc rulers. Kiá»Âm and his mother sought refuge under Ninh Bang Hầu, hoping for stability and a better life. His mother personally begged the general to take her son into service as a household retainer, pleased with his spirit, he agreed. He assigned Trá»Ânh Kiá»Âm to oversee the farming estates in the hamlet Thá» Liêu where he was responsible for raising livestock, including buffaloes and horses, something he was specialized and experienced in. During his daily routine, Trá»Ânh Kiá»Âm befriended a Cham man who also worked in the estate named Và © Thì An, who was an expert in training horses. Under his teachings, Trá»Ânh Kiá»Âm also learned how to recognise and train superior horses breeds himself.:
Ambitious, and dissatisfied with his role realizing that he had no real future of progression, one day Kiá»Âm stole the best horse from his masterâÂÂs stables and fled. Riding at full speed, he crossed the border into Mðá»Âng Sùng Cá» Là ©ng (modern-day Bá Thðá»Âc), which was then part of Ai Lao (Laos) where he intended to join a cousin Trá»Ânh Quang, who was already fighting under the army of Nguyá» n KimâÂÂs against the Mạc dynasty. Due to going hastily, he arranged plans for his mother to reunite with him once he was settled down. His mother, however, who was left behind, fled back to her home village in Vá» Quá»Âc knowing Ninh Bang Hau would be sworn with vengeance for this offense. When Ninh Bang Hầu discovered that Kiá»Âm had stolen his horse and fled, he felt betrayed and was enraged. He ordered his soldiers and the villagers of Sóc Sán and Biá»Ân Thðợng to hunt down Trá»Ânh Kiá»Âm and his mother no matter what, offering rewards for their capture. After an extensive search, they only managed to capture his mother. Ninh Bang Hầu gave her an ultimatum.
After searching, his mother found Kiá»Âm where she decided they needed to go into hiding immediately. They hid at her brotherâÂÂs house in the village of Biá»Ân Thðợng. However, when the village chief discovered them, much to their surprise, instead of turning him in, feeling pity, he chose to help Kiá»Âm. After discussing a plan among them, one night seeing a good opportunity, he threw a rock which signaled for Kiá»Âm to escape. He quickly crawled through several layers of fences then fled to the home of a contact named Nữu in Yên ÃÂá»Ânh. Nữu concealed Trá»Ânh Kiá»Âm by placing him into a large grain bin and covering it with rice where he was to be transported out the region. When Kiá»Âm later in life rose to power, Nữu had already died. In gratitude for his past kindness, Kiá»Âm rewarded NữuâÂÂs family with a great pension for ancestral offerings and daily expenses. Despite these efforts, the villagers eventually recaptured Kiá»ÂmâÂÂs elderly mother and handed her over to Ninh Bang Hầu. Three days later, he forced the village of Sóc Sán to place her in a bamboo cage, weighing it down with a large rock, and throwing it into the river where she drowned a slow and humiliating death. Kiá»ÂmâÂÂs close friend from the estate, Và © Thì An, learned of the execution and immediately sent his son, Và © ÃÂình Tùng, to inform Kiá»Âm. At first, Kiá»Âm feared it was a trap, but when he realized the truth, he was devastated. Overcome with grief, he wept and swore:
He then turned to Và © ÃÂình Tùng and said:
:
Early one morning, a fisherman named Mai, who had moved from ÃÂông Biá»Ân village to Ngạn Thðợng village, spotted a body floating in the river. He went home to fetch a hoe to bury it, but when he returned, he saw something mysteriousâÂÂa swarm of termites had gathered around the corpse, forming what looked like a burial mound. Word of this reached Kiá»Âm, whoâÂÂalong with his cousin Trá»Ânh Quáng and loyal friends Trá»Ânh Bá Di and Và © Thì AnâÂÂretrieved his motherâÂÂs body and performed funeral rites. Fearing that Mạc soldiers would desecrate her grave, he had Và © Thì An and his son wrap the body in a mat and secretly transport it through the ÃÂðá»Âng Cán Mountains to a hidden burial site in ÃÂá»Âng Rạng (Yên Viá»Ât Village) to rebury.
After Mạc ÃÂÃÂng Dung usurped the throne, the descendants of Lê dynasty officials and loyal members, especially those from Thanh Hoa, refused to accept his rule and continuously rebelled. Nguyen KimâÂÂa noble from a prestigious family that had served the Lê dynasty for generationsâÂÂfled to Ai Lao (modern-day Laos) to gather troops and plan the restoration of the Lê dynasty. By 1533, Nguyá» n Kim placed the son of Emperor Lê Chiêu Tông on the throne, naming him Lê Trang Tông. The new emperor granted Nguyá» n Kim the title Thái sð Hðng Quá»Âc Công (Grand Duke). This marked the beginning of the conflict between the Southern Court (Lê-Nguyá» n forces) and the Northern Court (Mạc dynasty).
Kim stationed his forces in Mðá»Âng Sùng, a region in Ai Lao. During this time, Kiá»Âm had already joined KimâÂÂs army and was already gaining a reputation as a renowned and skilled warrior who was quickly rising in the ranks. Kim summoned him one day and began questioning him, seeing that Kiá»Âm was articulate, brilliant, and exceptionally courageous, Kim quickly recognized his potential. Eventually, Kim appointed Kiá»Âm as Tri Mã Cá a (Commander of the Cavalry), placing him in charge of the militaryâÂÂs horses and entrusted him with leading soldiers into battle. Kiá»Âm and his forces stationed themselves in Vạn Lại and achieved a great victory against the Mạc army. According to âÂÂHistory of the Kingdom of ÃÂàng Ngoàiâ (Lá»Âch sá» vðáng quá»Âc ÃÂàng Ngoài) by Alexandre de Rhodes, when Mạc forces launched a massive attack on the capital, Kim and his army found themselves trapped in an enemy siege. In desperation, Kim made a promise:
âÂÂI will marry my daughter to whoever can break through the enemy lines and rescue me and my men!âÂÂ
Trá»Ânh Kiá»Âm mounted his horse and charged fearlessly into battle, cutting down enemy soldiers one after another and opened a path for KimâÂÂs army to escape. Keeping his word, Kim married his daughter Princess Ngá»Âc Bảo to Kiá»Âm and assigned him more important military duties, especially the training of cavalry for the resistance forces. In 1539, Kiá»Âm was assigned to escort Emperor Lê Trang Tông back to Vietnam from Ai Lao. Having himself heard of Kiá»ÂmâÂÂs extraordinary prowess and victories, Lê Trang Tông promoted him to ÃÂại Tðá»Âng Quân (Grand General) and granted him the title Dá»±c QuáºÂn Công (Duke). At that time, Kiá»Âm was 37 years old. The emperor viewed him as a trusted individual and in high esteem, granting him the military seal and placing him in charge of battles against the Mạc dynasty in Thanh Hoa Province. Kiá»Âm later secured a major victory against the Mạc forces at Lôi Dðáng.
After these successes, Kiá»Âm returned to his hometown to hold a grand banquet and pay respects to his ancestors. Duke, Lại Thế Vinh, the elder brother of Kiá»ÂmâÂÂs second wife Lại Ngá»Âc Trân, gifted him lands in Yên Hoằng Commune to build a residence and military base. In 1540, Nguyá» n Kim led his army to Nghá» An, expanding their influence. His growing reputation caused many local forces to surrender without resistance. The following year (1541), Mạc ÃÂÃÂng Dung died. Seizing the opportunity, KimâÂÂs forces launched an offensive, capturing Thanh Hóa and Nghá» An. By 1543, they had successfully recaptured Tây ÃÂô (modern-day Thanh Hóa Province) from the Mạc dynasty.
In 1545, a former general of the Mạc dynasty, Dðáng Chấp Nhất, poisoned Nguyá» n Kim, killing him. Before his death, Nguyá» n Kim entrusted full military command to Kiá»Âm because his two sons, Nguyá» n Uông and Nguyá» n Hoàng, were still too young to lead. With KimâÂÂs passing, all military power of the Lê dynasty ultimately fell into the hands of him.
Later that year, in August of the lunar calendar, Mạc Phúc Hải, the emperor of the Northern Court, ordered his General Mạc Phúc Tð to launch a surprise attack on Lê Trang TôngâÂÂs headquarters. As Mạc forces advanced to the Phù Chẩn River, Lê Trang Tông personally led his army to face them. Kiá»Âm, serving as Commander-in-Chief of the Imperial Army, led the vanguard forces. Where his army crushed the Mạc forces, killing a devastating number of enemy soldiers. General Phuc Tu fled back to the north in defeat. Later that year (1545), Emperor Lê Trang Tông granted Trá»Ânh Kiá»Âm the rank and title of:
He was also granted the noble rank of Thái Sð (Grand Mentor) and the title Lðợng Quá»Âc Công (Duke of Lðợng).
From that point onward, Kiá»Âm held absolute control over the Lê dynastyâÂÂs military and political affairs. Even though Emperor Lê Trang Tông remained on the throne, all important decisionsâÂÂsuch as military campaigns and government appointmentsâÂÂwere made by Kiá»Âm first, and the emperor would only approve them afterward. This marked the beginning of Kiá»ÂmâÂÂs dominance over Vietnam, eventually leading to the establishment of the Trá»Ânh Lords, who were the real rulers of Dai Viet for the next two centuries.
In 1546, Kiá»Âm withdrew his troops to Thanh Hóa, established a temporary royal court for Lê Trang Tông in Vạn Lại, and began recruiting brave and skilled warriors, training soldiers in mass, stockpiling provisions, and strategizing for battles against the Mạc dynasty. At this time, ÃÂại Viá»Ât was divided into two regions: from Thanh Hóa southward was under the rule of the Lê dynasty, commanded by Trá»Ânh Kiá»Âm; from Sán Nam northward belonged to the Mạc dynasty, known as the Northern Court. Whenever military campaigns were launched, Kiá»Âm led them and was victorious wherever he fought. As a result, many warriors seeking glory, honor, prestige, from Hoan and Diá» n (Nghá» An, à(Thừa Thiên, Huế), and Quảng (Quảng Nam, ÃÂàNẵng) flocked to join him, including notable figures such as Phùng Khắc Khoan, Lðáng Hữu Khánh, ÃÂinh Bạt Tuỵ, Nguyá» n Khải Khang, Nguyá» n Thiến, and Lê Khắc TháºÂn. The land of ÃÂi Châu (Thanh Hóa) gradually stabilized.
During the reign of Lê Thái Tá» the country was divided into five military districts: The Eastern District, Southern District, Western District, Northern District, and Hải Tây District. By the time of Lê Thánh Tông, the country was reorganized into 13 administrative provinces. When Mạc ÃÂÃÂng Dung usurped the Lê throne, the entire country fell under Mạc rule, except for 11 military districts in Tuyên Quang, which were controlled by Và © VÃÂn MáºÂt. Later, when Nguyá» n Kim launched his campaign, he first captured ÃÂi Châu (Thanh Hóa) and gradually took control of the southern territories, including Châu Hoan, Diá» n, and àLý (Nghá» An, ThuáºÂn Hóa). This resulted in Vietnam being divided into two rival dynasties, the Mạc and the Lê Restoration. Tuyên Quang, under the leadership of Và © VÃÂn MáºÂt, pledged allegiance to the Lê-Trá»Ânh faction.
According to The History of the Kingdom of ÃÂàng Ngoài, all power was in the hands of Trá»Ânh Kiá»Âm, while the emperor had no real authority:
In 1556, Emperor Trung Tông died without an heir. At that time, the main Lê royal bloodline had ended, prompting royal officials to discuss the matter. Some suggested selecting a descendant from the emperorâÂÂs maternal family, while others insisted that the throne should remain within the Lê paternal bloodline. Kiá»Âm then ordered a search for Lê descendants, eventually finding Lê Duy Bang, a fourth-generation descendant of Lê Trừ (the elder brother of Lê Thái Tá»Â), who was living in the village of Bá» Vá»Â, in ÃÂông Sán. Trá»Ânh Kiá»Âm brought him back and enthroned him as Lê Anh Tông. During Trá»Ânh Kiá»ÂmâÂÂs rule, the Lê Restoration Court only held two Confucian scholar examinations in 1554 and 1565. Regarding the military system, Trá»Ânh Kiá»Âm maintained the previous military structure, establishing five ÃÂô ÃÂá»Âc military commands and organizing troops into five military camps, each with different ranks and divisions. However, recruitment was limited to soldiers from Thanh Hóa and Nghá» An only.
In 1554, Kiá»Âm moved King LêâÂÂs temporary court to Biá»Ân Thðợng. Seeing an opportunity with morale high, he ordered his generals to launch a military campaign to reclaim Hóa Châu in the south. This region was controlled by a Mạc general, Hoàng Bôi. The Southern CourtâÂÂs army defeated and killed Hoàng Bôi, securing control over Hóa Châu, which included the provinces of ThuáºÂn Hóa and Quảng Nam. Afterward, Grand Chancellor Kiá»Âm appointed local leaders and officials to restore order, ensuring stability in the newly reclaimed lands.
By October 1558, Kiá»Âm proposed a long-term strategy to King Anh Tông. He believed securing the southern region would allow him to focus entirely on defeating the Mạc dynasty in the north. In his petition, he argued that ThuáºÂn Hóa was a crucial military stronghold with a resilient population and abundant resources. He recommended appointing Nguyá» n Hoàng, a capable and level-headed leader, as the governor of the region. The king agreed, granting Nguyá» n Hoàng full control over ThuáºÂn Hóa, except for the requirement to send annual taxes to the royal court. From this point on, Nguyá» n Hoàng worked alongside Bùi Tá Hán, the governor of Quảng Nam, to defend the southeastern frontier of the Lê dynastyâÂÂs stronghold.
In March 1568, Bùi Tá Hán died, and Kiá»Âm appointed Nguyá» n Bá Quýnh, a general from Nghá» An, to take his place as the regionâÂÂs military commander. By 1569, King Lê Anh Tông formally recognized Trá»Ânh Kiá»ÂmâÂÂs power, bestowing upon him the titles of Supreme General and Grand Duke, as well as the honorary title Supreme Father of the kingdom. By this time, Trá»Ânh Kiá»ÂmâÂÂs influence had completely overshadowed the royal court. Though he had not yet recaptured the capital, his leadership was instrumental in restoring the Lê dynasty. His growing power also marked the beginning of the Trá»Ânh familyâÂÂs rule as hereditary warlords (Chúa).
Later that year, Nguyá» n Hoàng traveled from ThuáºÂn Hóa to Thanh Hoa to visit the king and pay respects to Trá»Ânh Kiá»Âm. Their meeting was warm and friendly, with Trá»Ânh Kiá»Âm advising him:
In 1546, the Northern emperor Mạc Phúc Hải died, and his son Mạc Phúc Nguyên took the throne. However, because Phúc Nguyên was still young, factions within the court began plotting to overthrow him. Feeling unsafe, he abandoned the main royal palace in ThÃÂng Long and moved outside the city, throwing the capital into chaos.
After Emperor Lê Trang Tông of the Southern court died in 1548, his son Lê Trung Tông, still a child, ascended the throne. Because of the kingâÂÂs youth, General Kiá»Âm chose to focus on stabilizing the regions and protecting the people rather than launching any major northern campaigns. As a result, both sides of the conflict briefly experienced peace, and the people enjoyed a few years of stability. In 1550, Northern grand chancellor Lê Bá Ly, after being slandered at court, defected from the Mạc and surrendered to the Southern Lê court, following him over 13,000 troops from Sán Tây and Sán Nam. He also wrote letters encouraging other northern advisors and generals, like Nguyá» n Hữu Liêu and ÃÂặng Huấn, to follow his lead. According to historian Lê Quý ÃÂôn in âÂÂKiến VÃÂn Tiá»Âu LụcâÂÂ, this marked the beginning of the Mạc DynastyâÂÂs decline and the rise of the Lê armyâÂÂs reputation.
In 1551, Trá»Ânh Kiá»Âm assigned Lê Bá Ly to attack Sán Nam and Và © VÃÂn MáºÂt to attack Tuyên Quang, then convened with them in ThÃÂng Long. Before the campaign, he wrote a letter in the Nôm script, urging everyone to remember King Lê Thái Tá»ÂâÂÂs past efforts in expelling the Ming invaders and gaining independence for Vietnam, to now once again unite in supporting the Lê king and eliminate the Mac usurpers.
The three generals launched simultaneous attacks. In 1552, Trá»Ânh Kiá»Âm led troops to suppress the southwestern region, and Mạc general Nguyá» n Khải Khang surrendered. After capturing the citadel, he withdrew to Tây ÃÂô to avoid a surprise attack from Mạc reinforcements. In May 1552, Trá»Ânh Kiá»Âm launched an offensive from Há»§ng Hoá, crossing the Thao River to An Lạc. He defeated Mạc troops commanded by Prince Khiêm, Mạc KÃÂnh ÃÂiá»Ân. He then advanced to Xuân Canh Lâm Hạ, winning several more battles. Mạc Phúc Nguyên, frightened, fled to Kim Thành. The Lê army entered ÃÂông Kinh and held a banquet to reward the soldiers. They captured several prefectures in the Sán Tây and Sán Nam regions; the Mạc retained only the Eastern and Northern routes. Nguyá» n Khải Khang and Lê Bá Ly proposed bringing the emperor back to ThÃÂng Long, but Trá»Ânh Kiá»Âm believed the Mạc were still strong and public sentiment hadnâÂÂt fully shifted to the Lê. Therefore, he didnâÂÂt sign the petition. Upon reading the petition and understanding Trá»Ânh Kiá»ÂmâÂÂs intentions, the king ordered a retreat. Mạc Phúc Nguyên, upon hearing of the Southern armyâÂÂs withdrawal, dispatched troops to pursue them at Nam Công Mountain. However, Trá»Ânh Kiá»Âm defeated the Mạc pursuers and returned to Thanh Hoa. From then on, ÃÂông Kinh and the Sán Tây and Sán Nam regions reverted to Mạc control.
By August 1555, the Northern court regained strength. Emperor Mạc Phúc Nguyên ordered Mạc KÃÂnh ÃÂiá»Ân to invade Thanh Hoa, appointing Duke Thá» as commander of the Southern route army, leading 100 warships as the vanguard, advancing straight to the Thần Phù estuary. Sau Mạc KÃÂnh ÃÂiá»Ân há»Âi quân ÃÂóng á» sông ÃÂại Lại, Later, Mạc KÃÂnh ÃÂiá»ÂnâÂÂs forces camped at the ÃÂại Lại River, assigning Duke Thá» to station at Kim Sán. Prince Khiêm, Mạc KÃÂnh ÃÂiá»Ân, was a formidable opponent to Duke Lðợng, Trá»Ânh Kiá»Âm, and the LêâÂÂTrá»Ânh faction. As acknowledged by Lê historians in the âÂÂÃÂại Viá»Ât Sá» ký Toàn thðâÂÂ: âÂÂKÃÂnh ÃÂiá»Ân was benevolent, brave, intelligent, resourceful, perceptive, experienced in hardships, diligent, and loyal.
Trá»Ânh Kiá»Âm convened a meeting with his generals:
He instructed the villagers on both riverbanks to remain calm. He personally led troops to set up ambushes at Bạch Thạch Mountain phÃÂa Bắc Sông, lại sai binh tðợng hùng mạnh mai phục dðá»Âi núi Kim Sán, lại sai Thái úy Hùng quá»Âc công ÃÂình Công ÃÂá»Âc suất các tðá»Âng cà © cá»§a NhàMạc ÃÂầu hàng quân Nam triá»Âu làLê Bá Ly, Nguyá» n Khải Khang,... cùng quân bản bá» mai phục á» phÃÂa nam sông. Từ núi Yên ÃÂá»Ânh cho tá»Âi núi Quân Yên, north of the river, deployed strong elephant troops to ambush at the foot of Kim Sán Mountain, and ordered Grand Marshal Duke Hùng, ÃÂinh Công, to lead former Mạc generals who had defected to the Southern court, such as Lê Bá Ly and Nguyá» n Khải Khang, along with their troops, to ambush south of the river. From Yên ÃÂá»Ânh Mountain to Quân Yên Mountain, he assigned Phạm ÃÂá»Âc and Nguyá» n Quyá»Ân to lead naval forces to occupy the upper reaches from the Hữu Chấp River to the Kim Bôi River to create a strategic advantage. As the Mạc army passed through Kim Sán to ÃÂng TáºÂp market, they remained overconfident, unguarded, and their troops were known for playing music and singing, as if entering an uninhabited area.
At noon, ÃÂinh Công and Lê Bá Ly signaled with seven cannon shots, launching their attack; troops and war elephants from the lower river crossed to intercept the Mạc rear guard, while the upper river naval forces attacked the front, and troops from all sides overwhelmed the Mạc army. Duke Thá» had to jump into the river and was captured alive by Duke Triá»Âu, Và © Sð Thðá»Âc. Mạc general Vạn ÃÂôn Hầu and several dozen officers drowned; KÃÂnh ÃÂiá»Ân gathered the remnants and retreated to ThÃÂng Long. Trá»Ânh Kiá»Âm reported the victory to King Lê Trung Tông. The king ordered the execution of Duke Thá» and several dozen other Mạc generals at ÃÂá»Âng Lá»Âc Mountain.
In July 1557, Mạc Phúc Nguyên ordered Mạc KÃÂnh ÃÂiá»Ân to attack Thanh Hoa again, assigning generals Phạm Quỳnh and Phạm Dao to lead naval forces across the sea to attack Nghá» An. Mạc KÃÂnh ÃÂiá»ÂnâÂÂs naval forces reached the Thần Phù River and Tá»Âng Sán, Nga Sán Nga Sán regions, burning all floating bridges of the Southern court. Trá»Ânh Kiá»Âm stationed Duke Thanh at Nga Sán and Duke Thụy at Tá»Âng Sán, preventing the Mạc army from advancing. Trá»Ânh Kiá»Âm personally led troops, secretly moving along Yên Mô Mountain to the estuary, launching an attack on the Mạc armyâÂÂs rear, trapping them. During the battle, Trá»Ânh Kiá»Âm ordered Và © LÃÂng Hầu, Phạm ÃÂức Kỳ of Hoằng Hóa, to lead the vanguard. Encountering Mạc KÃÂnh ÃÂiá»ÂnâÂÂs ship, Phạm ÃÂức Kỳ leaped onto it, drew his sword, and cut the umbrella bearer in half, causing the body to fall into the river. KÃÂnh ÃÂiá»Ân, caught off guard, jumped into the river to escape. The Mạc army was defeated, with soldiers fleeing into the mountains; the Southern court captured many weapons. Mạc KÃÂnh ÃÂiá»Ân swam into a cave in Trá» Ná»Âi village, Yên Mô district, hiding for three days without food. One night, seeing a banana tree floating by the cave entrance, he clung to it, swam back, and fortunately reached Trinh Nữ wharf in Yên Mô, where someone rescued him, allowing him to return safely.
In 1569, in failing health, Trá»Ânh Kiá»Âm passed power to his eldest son, Trá»Ânh Coi. In 1570, Trá»Ânh Kiá»Âm died. In the same year, Trá»Ânh Coi was defeated by a Mạc army and was replaced by his younger, more capable brother, Trá»Ânh Tùng.
