Pfc. Willie Godboldt (who died of his wounds shortly thereafter). Two M60 crews (under Spec. James Comer and Spec. 4s Clinton Poley, Nathaniel Byrd and George Foxe) were instrumental in preventing the PAVN advance from completely overrunning Geoghegan's lines. Following this attack, Charlie Company's 3rd Platoon under Lt. William Franklin came under assault. C Company's commander, Capt. Edwards was seriously wounded and Lt. John Arrington assumed command of the company and was himself wounded while receiving instructions from Edwards. C Company's command then passed to Platoon Sgt. Glenn A. Kennedy. Lt. Franklin was also seriously wounded. The battalion was being attacked in two directions. Three-pronged attack At 07:45, the PAVN launched an assault on Crack Rock, near its connection with the beleaguered C/1/7. Enemy fire started to hit the 1st Battalion command post, which suffered one medic killed and several other troops wounded (including one of Moore's own radio operators, Spec. 4 Robert Ouellette). Under heavy attack on three sides, the battalion fought off repeated waves of PAVN infantry. It was during this battle that Spec. Willard Parish of Charlie Company, situated on Delta Company's lines, earned a Silver Star for suppressing an intense PAVN assault in his sector. After expending his M60 ammunition, Parish resorted to his .45 sidearm to repel PAVN forces that advanced within of his foxhole. After the battle, more than 100 dead PAVN troops were discovered around his position. As the battle along the southern line intensified, Lt. Charlie W. Hastings (U.S. Air Force liaison forward air controller) was instructed by Moore (based on criteria established by the Air Force) to transmit the code phrase "Broken Arrow", which relayed that an American combat unit was in danger of being overrun. In so doing, Hastings was calling on all available support aircraft in South Vietnam to come to the 1st Battalion, 7th Cavalry's defense, drawing on a significant arsenal of heavy ordnance support. On Charlie Company's broken lines, PAVN troops walked the lines for several minutes, killing wounded Americans and stripping their bodies of weapons and other items. It was around this time, at 07:55, that Moore ordered his men to throw colored smoke grenades to mark the battalion perimeter. Aerial fire support was then called in on the PAVN at close range – including those along Charlie Company's lines. Shortly afterwards, Moore's command post was subjected to a friendly fire incident by two F-100 Super
