 Premature Tet Offensive attacks at Nha Trang and Qui Nhơn on the morning of 30 January led to the cancellation of the Tết ceasefire, but many ARVN soldiers were already away on leave, meaning that defenses in and around Huế were undermanned.On learning of the cancellation of the ceasefire, Trưởng ordered his headquarters staff to remain at the Mang Ca compound that night, he sent three platoons from the "Hac Bao" Reconnaissance Company to guard the provincial headquarters, the power station and the prison in the new city.He split up two more platoons to reinforce security at the various gates leading into the Citadel.
