BosnianâÂÂRagusan War (1403âÂÂ1404), sometimes called Second BosnianâÂÂRagusan War, was a military conflict fought between the Kingdom of Bosnia and the Republic of Ragusa between 1403 and 1404, which ended with a treaty signed officially in 1405. In 1403, Stephen Ostoja of Bosnia sided with King Ladislaus of Naples in his plights against the Hungarian King Sigismund, Bosnia's liege. King Ostoja led a war against Ragusa, at the time an ally of Hungary.
RadiÃÂ SankoviÃÂ led the attacks on Dubrovnik in the name of Stephen Ostoja. Sandalj HraniÃÂ captured and blinded RadiÃÂ, and held him in prison until his death in 1404. Among the fallen noblemen were Vukosav NikoliÃÂ and the Duke of Slano, whose name has been unfortunately lost to time.
The Ragusans set fire to à  umet and à ½rnovnica, so the Bosnian army retreated.
