 Leaving Company A behind to secure the MACV Compound, Gravel took Company G, reinforced by the three M48 tanks from the 3rd Tank Battalion and a few ARVN M24 light tanks from the 7th Armored Cavalry Squadron, and attempted to cross the Trường Tiền Bridge, the main bridge over the Perfume River.Gravel left the armor behind on the southern bank to provide direct fire support.As he later remembered, the American M48s were too heavy for the bridge and the ARVN tankers "refused to go."
