Crossing the mouth of Dam Cau Hai Bay on a pontoon bridge to be constructed by ARVN engineers and moving along the beach to Highway 1, they would cross over the Hải Vân Pass and on to Da Nang. No trucks, tanks, or guns could make this march; all would have to be disabled or destroyed. The division would protect the column by blocking in Phu Thu District. By the time these orders were issued, what was left of the population of Hue was streaming toward Tân Mỹ Base to take any available boat or ship out of Thua Thien Province. I Corps Forward commanded by Thi, established its command post in Tân Mỹ, together with the command posts of the Marine Division and the 147th Marine Brigade. The 7th Marine Battalion deployed there to secure the port and the command posts. The division withdrew from the Troui-Nui Bong sector. The 15th Ranger Group, which had held the Troui River for the pulled back to Phu Bai Combat Base with heavy casualties. The 54th Regiment withdrew from the Nui Mo Tau sector to Camp Eagle, southeast of Huế near Highway 1. The 3rd Regiment withdrew from its forward positions on the Son Hue Trach and assembled in Nam Hoa, south of Huế. The 51st Regiment pulled back and located just west of the city while the division headquarters and the 1st Regiment, which had suffered moderate casualties in the Nui Bong sector, were around Huế. 1192:, Trưởng was directed to stop the evacuation of Hue and to defend enclaves at Huế, Da Nang, Chu Lai and Quang Ngai City. He could, when forced, surrender Chu Lai and Quang Ngai, but he was to defend Huế and Da Nang at all costs. When Trưởng returned to his headquarters on 20 March, he turned around the displacing 175mm. batteries moving to Da Nang and stopped the evacuation of ammunition from Huế. The Imperial City would be defended despite the fact that PAVN artillery had, on 19 March, already struck inside the Citadel and Highway 1 was clogged with the southbound traffic of thousands of refugees. The contracted organization for the defense of Huế, under the command of Thi, was divided between the deputy commander of the Marine Division, Colonel Tri, who was responsible north of Hue, and the 1st Division commander Diem, south of the city. Tri's outposts were just inside the Thua Thien-Quang Tri boundary, nearly 30 km northwest of Huế. Here, under the direct command of the 14th Ranger Group, were the 77th Ranger Battalion, seven RF battalions, and a troop of armored personnel carriers of the 17th Armored Cavalry Squadron. The four Marine battalions of the 147th Brigade were in the vital Bo Corridor, within light artillery range of the Citadel, while the 78th and 79th Ranger Battalions were on outposts 10 km west of the Marines. South of the Marines, on the high ground at Fire Support Base Lion (also called Nui Gio) ( 654:

Vietnamese Marines had only advanced 400 metres. Meanwhile, the ARVN 3rd Regiment fought off a PAVN counterattack in the northwest corner of the Citadel. On 17 February the Vietnamese Marines and 3rd Regiment resumed their attacks south, while the Black Panther Company was moved to support the right flank of the 1/5 Marines, over the next 3 days these forces would slowly reduce the PAVN's perimeter. On 22 February after a barrage of 122mm rockets the PAVN counterattacked the Vietnamese Marines who pushed them back with the support of the Black Panther Company. On the night of 23 February the PAVN attempted another counterattack but were forced back by artillery fire and the 3rd Regiment launched a night attack along the southern wall of the Citadel, at 05:00 they raised the South Vietnamese flag on the Citadel flag tower and proceeded to secure the southern wall by 10:25. Trưởng then ordered the 2nd Battalion 3rd Regiment and the Black Panther Company to recapture the Imperial City and this was achieved against minimal resistance by late afternoon. The last remaining pocket of PAVN at the southwest corner of the Citadel was eliminated in an attack by the 4th Vietnamese Marine Battalion in the early hours of 25 February. As a result of the battle this division had earned several commendations from the RVN Government as well a

with heavy PAVN losses, but the Phú Lộc sector, taking the brunt of the attack, began to crumble. In the area of the 1st Regiment, the PAVN 18th Regiment, 325th Division, supported by the 98th Artillery Regiment, took Hill 350 and drove on to assault Nui Bong. Although the mountain changed hands three times that afternoon, the 2nd Battalion, 1st Regiment, controlled it on 22 March. Other formations of the 325th, notably the 101st Regiment, forced the 60th Ranger Battalion, 15th Group, from Hill 500 west of Phú Lộc, and supporting artillery interdicted Highway 1. A stream of refugees began piling up along the road northwest of Phú Lộc. By evening, however, one lane was opened for traffic to Da Nang. To the west, in the hills around Mo Tau, the 27tst Independent Regiment and the 29th Regiment of the 304th Division, both operating under the 324th Division, attacked the 54th Regiment and were repelled. A prisoner from the 27lst said that casualties in his regiment were very heavy, that the 9th Battalion was nearly destroyed. PAVN attacks continued all along the Thua Thien front on 22 March. An ARVN counterattack to recapture Hill 224, a key position in the Nui Mo Tau sector, failed. The population of Huế had declined to only 50,000, and the Hải Vân Pass was clogged with desperate people trying to escape.

371:. The number and intensity of strikes, marches, and rallies steadily increased, fueled by soldiers, police, and local officials loyal to Thi. By the beginning of April Struggle Movement forces appeared to control most of Huế, Da Nang and Hoi An and had the support of the I Corps headquarters and the division. At the same time, South Vietnamese combat operations in the northern zone began to peter out, and the danger that the crisis presented to the war effort became evident. As the new division commander, Nhuận placed infantry and armored forces in blocking positions along Route 1, between Huế and Da Nang, and stood ready to reinforce Struggle units in Da Nang the situation inside the city was tense. The commander of the Quang Nam Special Zone, Colonel Dam Quang Yeu, headed the rebel military units that, according to US estimates, included an infantry battalion from the 51st Regiment, three Regional Forces companies, eleven Popular Forces platoons, and six armored vehicles, plus about 6000 South Vietnamese administrative troops and 200 military police. When Yeu quickly positioned some of his units on the approaches to the downtown area, the start of civil war seemed imminent. 580:, but PAVN defensive fires forced them to fall back. Unable to enter the Citadel, the two battalions established their night positions outside the southeast wall of the old City. PAVN/VC forces surrounded the 1st and 4th Battalions of the regiment, operating to the southeast, as they attempted to reinforce the units in Huế. Captain Phan Ngoc Luong, the commander of the 1st Battalion, retreated with his unit to the coastal Ba Long outpost. At Ba Long, the battalion then embarked upon motorized junks and reached the Citadel the following day. The 4th Battalion, however, remained unable to break its encirclement for several days. South of the city, Lieutenant Colonel Phan Hu Chi, the commander of the 7th Armored Cavalry Squadron attempted to break the PAVN/VC stranglehold. He led an armored column toward Huế, but like the other South Vietnamese units, found it impossible to break through. With the promise of U.S. Marine reinforcements, Chi's column, with three tanks in the lead, tried once more. This time they crossed the An Cuu Bridge over the Phu Cam Canal ( 1112:, I Corps Deputy Commanding General and commander north of the Hải Vân Pass, detached a battalion from the 51st Infantry and returned it to the 1st Division to reinforce the Song Bo defenses. The 1st Division Commander, Brigadier general Le Van Than, further reinforced the 3rd Regiment with a battalion of the 1st Infantry Regiment. The line stabilized toward the end of the year, but not until after Trưởng had accomplished the removal of Than and replaced him with Colonel Nguyen Van Diem. Diem took command of the division on 31 October but could make no noticeable headway in solving the division's tactical and morale problems. These were too much the results of conditions beyond the control of the commander: an extended front under continuous enemy pressure, the debilitating effects of cold, wet, typhoon weather; inadequate supply to the forward infantry outposts; and the worsening economic straits in which the soldiers found themselves. 1223:) was the 51st Regiment, with two of its battalions. Diem's responsibility began southwest of his 51st Regiment, which was attached to Tri's command. The 3rd Regiment, with two battalions, held the high ground around Firebase Birmingham, above the Song Huu Trach, south of Huế. East of the 3rd Regiment, the 54th Regiment with two of its battalions defended the Nui Mo Tau sector, while the reinforced 1st Regiment extended the line southeast to the Nui Bong area. The 1st Regiment had, in addition to its own three battalions, one battalion of the 51st Regiment, a company of M48 tanks and a troop of armored personnel carriers. The 15th Ranger Group, with its three battalions and one battalion of the 3rd Regiment, dug in on the hills above Highway 1 west of Phú Lộc District Town. The 258th Marine Brigade, with two battalions, was also near Phú Lộc, while the 914th RF Group of three battalions guarded the Hải Vân Pass. 938:– the largest helicopter assault of the Vietnam War. Only one helicopter was downed by anti-aircraft fire as the troops combat assaulted into LZ Hope, four kilometers northeast of Tchepone. For two days the two battalions searched Tchepone and the immediate vicinity, but found little but the bodies of PAVN soldiers killed by air strikes. PAVN responded by increasing its daily artillery bombardments of the firebases, notably Lolo and Hope. During the extraction of the 2nd Regiment, 28 of the 40 helicopters participating were damaged. Official ARVN sources stated that the division lost 491 dead during the operation, however division officers in private conversations with American officers said that they had lost at least 775 of their men in Laos. 628:

On 6 February the 1st Battalion captured the An Hoa Gate on the northwest corner of the Citadel and the 4th Battalion captured the southwest wall. On the night of the 6th, the PAVN counterattacked, scaling the southwest wall and pushing the 4th Battalion back to Tây Lộc.

The Hac Bao Reconnaissance Company was forced from Hill 50 southwest of Nui Bong. Diem reacted by dispatching the 15th Ranger Group with the 61st and 94th Ranger Battalions to reinforce the line and recover lost positions. The 61st was ambushed en route, sustained moderate losses, but recovered to join the 94th in a counterattack on 10 March.

Although the PAVN battalion penetrated the division compound, an ad hoc 200-man defensive force of staff officers and clerks staved off the enemy assaults. General Trưởng called back most of his Black Panther Company from the airfield to bolster the headquarters defenses, which kept division headquarters secure. Trưởng called in reinforcements ordering his 3rd Regiment; the 3rd Troop, 7th ARVN Cavalry; and the 1st ARVN Airborne Task Force to relieve the pressure on Mang Ca. Responding to the call at 576:
