Under sporadic but sometimes heavy enemy mortar attacks, U.S. and allied forces strengthened their defenses, as there were no significant ground probes on 10–11 May. Allied defenses at Khâm Đức were strengthened but the PAVN occupied the surrounding high ground, where they could target allied ground targets and support aircraft with a high level of accuracy.
