lines 20 minutes after the first attack as flares dropped from American C-123 Provider aircraft illuminated the battlefield to B Company's advantage. For around 30 minutes B Company fought off the PAVN advance with a combination of small arms and Lund's skilled organization of artillery strikes. Shortly after 05:00 a third attack was launched against B Company, which was repelled by Lt. James Lane's platoon within 30 minutes. At almost 06:30 the PAVN launched a fourth attack on Diduryk's men – this time in the vicinity of B Company's command post. Again, Lund's precision in ordering artillery strikes cut down scores of PAVN soldiers, while Diduryk's men repelled those who survived using rifle and machine gun fire. At the end of these attacks, with daybreak approaching, Diduryk's Company had only six lightly wounded men among its ranks – with none killed. LZ X-Ray secured At 08:30, Gen. DePuy asked Gen. Knowles if he had plans for exploitation of yesterday's strike, and if he had plan to commit another battalion for a total of 5 – besides the 1/7, 2/7, 2/5 and 1/9 Air Cav Battalions in the area. At 09:15, Knowles wanted the cavalry units on the ground to organize an exploitation of B-52 strike target operation. Moore responded that he had plans to send in 1st Cav, however at the present time all units are engaged. Around 10:30 a.m., 1st Battalion, 7th Cavalry received orders to withdraw from the battle zone while 2nd Battalion, 7th Cavalry and 2nd Battalion, 5th Cavalry took up defensive positions for the night. According to the assessment of ARVN Gen. Nguyen Vinh Loc, at the LZ X-Ray battle, the PAVN did not have anti-aircraft weapons and heavy mortars and had to resort to "human wave" tactics: "The enemy has lost nearly all their heavy crew-served weapons during the first phase ... Their tactics relied mostly on the 'human waves.'" The battle was ostensibly over. The PAVN forces had suffered hundreds of casualties and were no longer capable of a fight. U.S. forces had suffered 79 killed and 121 wounded and had been reinforced to levels that would guarantee their safety. Given the situation there was no reason for U.S. forces to stay in the field, their mission was complete and a success. Moreover, Colonel Brown (3rd Brigade commander), in overall command, was worried about reports that additional PAVN units were moving into the area
