 Whether the PAVN 2nd Division had been rendered ineffective or not was uncertain, as U.S. military intelligence did not know the whereabouts of the enemy unit or their intentions.The PAVN had been fighting continuously since January 1968 with U.S. and other allied military forces in I Corps, so their resupply capabilities were overstretched and their soldiers were not given the opportunity to rest before the Tet Offensive.Thus, following the failed attack on Đà Nẵng, PAVN General Chu Huy Mân, Commander of Military Region 5, made the decision to pull the 2nd Division into the mountains where they could rest, resupply, and integrate replacements before going on the offensive again.
