 Serbian Territorial Defense forces set up barricades in the town and tried to seize the strategically important bridge linking the town with Croatia, prompting the local Croats and Muslims to form a joint headquarters, and to request assistance from the Croatian Army, based just across the border in Slavonski Brod.According to a local report, 200 shells fell on Bosanski Brod on the first day of the Serb attack.Neither side managed to prevail, and the Yugoslav People's Army (JNA) sent its 327th Motorized Brigade to the city.
