In his memoir, Nicholas Warr, who in 1968 was a relatively new Marine platoon leader, tells the story of the battle for Hue's Citadel, the bloodiest and most famous episode of the recapture of Hue by the American and South Vietnamese forces.
The Citadel, the walled city of the emperor, lay in the heart of the imperial capital of Hue. It was there that the Communists established their main stronghold after the success of their initial attack during the Tet Offensive. The first attempt by the Americans and the ARVN to retake the Citadel from them ended in failure, so in the third week of February, South Vietnamese and American soldiers entered the Citadel and engaged in a difficult urban battle – block by block, yard by yard, house by house. Warr participated in this terrible fighting as the commander of Charlie Company, First Battalion, Fifth Marines.
The Marines began their offensive on the morning of February 13. They sent two companies to clear each building on the way, as a third company was kept in reserve. Tanks and Ontos provided the needed fire support. Unaware that the ARVN paratroopers had withdrawn, though, the Marines found themselves alone against a host of North Vietnamese soldiers. With tanks in the lead, they moved forward, but could not even reach their line of departure because the North Vietnamese, who had constructed spider holes along the old walls, bombarded them with automatic fire, grenades, B-40 rockets, and mortars. The best news of the day was the successful erection of a pontoon bridge across the Perfume River to replace the damaged one, allowing the shipment of food and supplies into the old city.
On February 15, the Marines achieved some progress by capturing a tower along the wall in their sector. Aided by A-4 fighter-bombers during another break in the weather, the Americans took and held the structure after hand-to-hand fighting and heavy casualties. The battalion pushed forward the next day, gaining a few more buildings. As the author observes, the North Vietnamese in that part of the city fought better and employed more sophisticated tactics than those encountered south of the river. They had dug trenches and spider holes, used roadblocks, and did not hesitate to counterattack the Americans to regain key positions. As Warr explains, the poor weather and limited effect of heavy artillery against the stone structures forced the Marines to rely on mortars and armor, which resulted in a large number of casualties among the armor crews. The battle for Hue was not over until February 25.
As the author argues, the armored forces proved to be an essential element in the hard-won victory at Hue. Tanks brought the traditional firepower and mobility to the battle with heavy enough armor to protect their crewmen from most of the North Vietnamese weapons. The M48 tanks in particular were able to survive a huge amount of damage and keep fighting. This ability to withstand damage allowed the M48 tanks to fight throughout the battle after makeshift repairs and rotating crews. Furthermore, the fire control, loading, and driving were simple enough to allow inexperienced personnel to ride tanks into combat when there were not any replacement armor crewmen available. The light, fast M50 Ontos armored vehicles, on the other hand, could maneuver in the narrow streets near the Citadel.
Warr paints in graphic terms how bitter and bloody the recapture of Hue was with its house-to-house fighting that destroyed virtually the whole city and heavy casualties on both sides. He speaks fondly of his fellow Marines, especially of the Gunny, Charlie Company's gunnery sergeant, an admired and respected veteran of the Second World War and the Korean conflict. I cannot say that I appreciate Warr's strictly pro-American stance on the Vietnam conflict and his complete avoidance of the suffering of Hue civilians, but his first-person narrative offers a glimpse into the thought process of a military man. He has a good grip on the tactics that the Marines employed, although at times he is short-sighted.
For instance, he claims that the Americans were reluctant to send the Army with artillery to Hue because they did not want to destroy the beautiful, historical city, and this is why the Marines were left to fight as they could. In reality, though, the American commanders did not have any scruples about razing the city to the ground. It was just that the Communist attack on Hue came as a complete surprise. There were only Marine units and an MACV compound stationed inside. Had they been prepared for the battle, the Army commanders would not have left the Marines to struggle by themselves.
PHASE LINE GREEN is a fine attempt to recreate the battle for Hue's Citadel. Warr delivers less than he promises, and his work is not the definitive account of the battle of Hue, though. This book will appeal to those who like war memoirs focusing mainly on soldier camaraderie, personal perspectives, and a patriotic stance on the conflict, with only an occasional dive into tactics. As the author tells in the introduction, he wrote it after his therapist advised him to put the memories that haunted him on paper to get them off his chest.
