The second battle during the Bosnian war took place in 1994 and was fought between the Army of the Republic of Bosnia and Herzegovina (ARBiH) and the Croatian Defence Council (HVO) on one side and the Army of Republika Srpska (VRS) on the other from 20 October to 3 November 1994. It marks the first tangible evidence of the Bosniak–Croat alliance set out in the Washington Agreement of March 1994, brokered by the United States to end the Croat–Bosniak War fought between the ARBiH and the HVO in Bosnia and Herzegovina. On 29 October, the HVO decided to attack, as it considered the ARBiH had directly threatened the strategic Kupres plateau. The HVO launched its offensive, codenamed Operation Cincar ("Operacija Cincar"), on 1 November. Following a brief lull in the ARBiH advance, thought to be brought on by a variety of causes and a direct request by the president of Bosnia and Herzegovina Alija Izetbegović to the ARBiH to cooperate with the HVO, commanding officers of the two forces met to coordinate their operations for the first time since the Washington Agreement. Kupres itself was captured by the HVO on 3 November 1994. Besides the political significance of the battle for future developments of the war in Bosnia, the battle was militarily significant for planning and execution of Operation Winter '94 by the Croatian Army (HV) and the HVO aimed at relieving the siege of Bihać in late November and December 1994. Territorial gains made by the HVO and the ARBiH in the Battle of Kupres safeguarded the right flank of Operation Winter '94.
