Lữ Mộng Lan (28 September 1927 – 28 May 2021) was a Lieutenant general of the South Vietnamese Army of the Republic of Vietnam (ARVN).
Lữ was born in Quảng Trị, French Indochina on 28 September 1927.
In 1944, he earned a Diplome D'Etudes Primaires Superieures Indochinoise (DEPSI), from Lycee Khai Dinh, located in Huế.
He served as Company commander, 1951 in the Vietnamese National Army then as Deputy Battalion commander, 1952; Regimental Chief of Staff, 1954; Division Chief of Staff, 1955.
In the ARVN in 1957, he graduated from Command and General Staff School, Fort Leavenworth. He served as Deputy Chief of Staff for Operations, Joint General Staff from 1958. He was then appointed commander of the 25th Division in 1962. He was appointed commander of the 23rd Division in 1964. He was appointed commander of the 10th Division in 1965.
By the end of 1965 the US advisers to the 10th Division regarded Lan as "moody and vacillatory" and "a marginal commander who would have to be worked with." They gave Lan high marks for his "perceptiveness and dexterity in civil affairs and troop morale" but saw his interest in local politics as too distracting. Although they found his three regimental commanders "capable and willing people," they felt that it was too early to judge if the Division was going to jell into a fighting unit. COMUSMACV General William Westmoreland predicted that combined operations with the US 1st Infantry Division and the 173rd Airborne Brigade would inspire the Division to higher standards.[1]
From September 1966 he served as the deputy chief of staff for training and director of the Central Training Command.[1]
In March 1968 he succeeded Nguyễn Phước Vĩnh Lộc as II Corps commander, he was not necessarily regarded as an improvement by MACV. As commander of the 25th, 23rd and 18th Divisions between 1962 and 1966, he had received poor ratings from almost all of his American advisers, he was, however, an ardent supported of President Nguyễn Văn Thiệu and could be expected to follow the dictates of the Saigon government more closely than his predecessor.[1]
In August 1970, Thiệu replaced Lan as II Corps commander with General Ngô Du.[1] Lan became inspector general of the armed forces and later commandant of the National Defense College.[1]
Lữ died in Virginia on 28 May 2021, at the age of 93.[2]
