VC forces around Huế included six main-force battalions, while two PAVN regiments operated in the area. As the battle unfolded three more PAVN regiments redeployed from Khe Sanh arrived as reinforcements. The North Vietnamese plan of attack on Huế involved intensive preparation and reconnaissance. Over 190 targets, including every government and military installation on both sides of the river would be hit on January 31 by a force of five thousand. Other forces would block American and ARVN reinforcement routes, mainly Highway 1. Over half of the ARVN 1st Division was on holiday leave and PAVN commanders believed the population of Huế would join the fight as a part of the General Uprising.
