Infanterie-Regiment Bremen (1. Hanseatisches) Nr. 75 was an active infantry regiment in the Prussian Army (1866âÂÂ1871) and the Imperial German Army (1871âÂÂ1918).
By an A.K.O. (Allerhöchste Kabinettsorder) dated 27 September 1866, which is considered the official foundation day of the regiment, a new Prussian regiment was formed after the Austro-Prussian War from companies of the Pomeranian Regiments No. 1, 3, 5 and 7 in Stettin on 3 November 1866. It was formed into a musketeer battalion in Harburg and a fusilier battalion in Stade and called Infanterie-Regiment Nr. 75.
As a result of the military convention between the Kingdom of Prussia and the Free and Hanseatic City of Bremen on 27 June 1867, the "Bremen" Fusilier Battalion, founded in 1813, was incorporated in the army of the North German Confederation. From this point on, this battalion formed the 1st (musketeer) battalion of the regiment. The regiment was renamed to 1. Hanseatisches Infanterie-Regiment Nr. 75. After 1893, both musketeer battalions were stationed in Bremen, while the fusilier battalion remained in Stade.
In the Franco-Prussian War, the regiment fought as part of the 17th Infantry Division in the battles of Noisseville, Loigny-Poupry, Orléans, Beaugency and Le Mans, and in the sieges of Metz and Paris. During this war, the regiment suffered a total of 26 officer casualties, including one medical officer (5 killed in action, 2 died illness, 19 wounded), as well as 534 casualties among non-commissioned officers and men (110 killed in action, 54 died of illness, 16 missing and 354 wounded). Four officers were awarded the Iron Cross 1st Class. The Iron Cross 2nd Class was awarded 169 times.
The regiment remained part of the peacetime 17th Division. It was renamed from the 1. Hanseatisches Infanterie-Regiment Nr. 75 to Infanterie-Regiment Bremen (1. Hanseatisches) Nr. 75 on 5 September 1904.
The regiment spent the entirety of World War I, except for some temporary detachments, as part of the 17th Infantry Division on the Western Front. An estimated 19,735 men served in the active regiment over the course of the war. Approximately 3,600 members of the regiment died during the conflict.
Two officers of the regiment, Oberstleutnant Wilhelm Hagedorn and Major Walter Caspari, were decorated with the Pour le Mérite, Prussia's highest military honor for officers. Five non-commissioned officers were decorated with the Military Merit Cross, Prussia's highest military honor for non-commissioned officers and other ranks. Sixteen officers, including Hagedorn and Caspari, were decorated with the Knight's Cross of the Royal House Order of Hohenzollern with Swords. The Iron Cross 1st Class was awarded to 79 officers and 105 non-commissioned officers and other ranks.
Several years after the war, former members of the regiment formed a veterans organization Kameradschaftsbund der Fünfundsiebziger (from 1939 to 1943: Traditionsverband des Ehem. Infant.-Reg. "Bremen" (1. Hans.) Nr. 75) which published a newsletter, Kameradschaftsbund der 75er. There was also a separate officers association. Following the war, the regiment was perpetuated in the Reichswehr by 1. Kompanie/16. Infanterie-Regiment (6. Division, based in Münster).
