In 1992, the Croat-Bosniak conflict erupted in Bosnia and Herzegovina, just as each was fighting with the Bosnian Serbs. The war was originally fought between the Croatian Defence Council and Croatian volunteer troops on one side and the Army of the Republic of Bosnia and Herzegovina (ARBiH) on the other, but by 1994, the Croatian Army had an estimated 3,000 to 5,000 troops involved in the fighting. Under pressure from the United States, the belligerents agreed on a truce in late February, followed by a meeting of Croatian, Bosnian, and Bosnian Croat representatives with US Secretary of State Warren Christopher in Washington, D.C. on February 26, 1994. On March 4, Franjo Tuđman endorsed the agreement providing for the creation of Federation of Bosnia and Herzegovina and an alliance between Bosnian and Croatian armies against the Serb forces.
