For months leading up to the attack the level of enemy activity in the area had been low and contacts were infrequent. The lack of significant recent engagements, along with preparations to turn the FSB over to ARVN units, had given the U.S. soldiers in the area a false sense of security. The sapper attack was sharp and very successful, with repercussions up the 23rd Infantry Division's chain of command, as the battle was described as a "rampage of VC who threw satchels at the command bunker, knifed Americans in their sleep and destroyed all communications equipment". Army Chief of Staff William Westmoreland was tasked with investigation of the attack, citing clear dereliction of duty, lax behavior and failure of officer leadership as the reasons. Charges were brought against six officers, including the 23rd Division Commander and Assistant Commander.
