 The new combat headquarters, staffed by high-ranking officials from the Trị-Thiên-Huế Front, local party members, and military officers from the units involved in the attack, had authority over the city and the three districts that surrounded it.On 28 January, the PAVN/VC units tasked with attacking the new city began moving into position 48 hours earlier than the northern wing tasked with attacking the Citadel, because it had a longer distance to march and more difficult terrain to cross.The 804th Battalion, 4th Regiment, began marching from Phú Lộc to a mountain camp south of Huế where the majority of the southern wing was gathered.
