aggressive ARVN military defenses. However, VC units began to engage ARVN forces and succeeded in isolating IV Corps from Saigon which put an end to the "secret section" plan. When President Minh announced the surrender of South Vietnam, IV Corps started to disintegrate. Both Lê Văn Hưng and IV Corps commander Nguyễn Khoa Nam disagreed with the surrender order. At 8 pm, VC units captured some regional districts in Mekong Delta. Although Lê Văn Hưng and a number of ARVN soldiers planned to continue to battle against VC units in Can Tho, many residents of Can Tho opposed continued resistance believing the VC would start shelling Can Tho causing numerous casualties in the city. Lê Văn Hưng agreed to stand down the defense of Can Tho due to the poor options for escape or prolonged defense. Around 8 P.M, Lê Văn Hưng told his remaining soldiers that he did not want to endure a siege similar to what he had experienced at An Lộc in 1972, he later committed suicide and the defense of Can Tho was finished. IV Corps was dissolved shortly after the death of Lê Văn Hưng. On the same day, Brigadier General Trần Văn Hai committed suicide in Dong Tam Base Camp. Both ARVN generals in the Mekong Delta, Le Van Hung and Nguyen Khoa Nam, committed suicide after the surrender. On the early morning of 1 May 1975, Major General Nguyễn Khoa Nam committed suicide at his IV Corps headquarters in Can Tho after hearing of Lê Văn Hưng's suicide. Conclusion By 3 May 1975, North Vietnamese forces controlled all of South Vietnam, just 55 days after opening their attack on Buôn Ma Thuột. Since the end of the war, there has been much historical recrimination and discussion as to how and why such a lopsided victory had occurred. Four main lines of thought have remained particularly viable, all of which possess some validity, but all are also open to argument. The first argument is that the Paris Peace Accords that ended the direct American participation in the war was seriously flawed, because it permitted the North Vietnamese to maintain their forces within territorial South Vietnam after the signing of the agreement, thereby dooming the ceasefire. The second argument is that the refusal of the United States government to take promised military action in the face of North Vietnamese violations of the ceasefire was key
