Ho Chi Minh was fighting for what was North Vietnam immediately after WW2 when the French tried to keep Indo China as part of their Empire. As for the 'Free South' I think that may well be clouded by your view of history. When the US Forces returned to the US Vietnam became 1 country ruled from Hanoi. This was in April 1975.
North Vietnamese Tanks rolled through the gates of the Presidential Palace in Saigon in April, 1975. The President of South Vietnam, Nguyen Van Thieu, fled the country in the days before the country fell to North Vietnam, leaving a successor to surrender.
30 April 1975.
To help preserve it from a communist NORTH Vietnamese take-over.
Communist North Vietnam, with help from the Chinese, was trying to take over democratically controlled South Vietnam.
It provided a force to assist the South Vietnam government resist the North Vietnamese attempt to take it over.
The north Vietnamese were fighting with the south Vietnamese because the Viet-min (north) wanted to impliment a communist government and the Viet-cong (south) wanted to remain as they were. The USA interfene and made the whole thing worse.
He did not want the Vietnamese to take over the french colony of Indochina
No, they only got into the U.S. Embassy compound in Saigon. They DID take control of the city of Hue for three weeks, resulting in house-to-house street fighting. This was the only city the North Vietnamese troops were successful in occupying - because it was the city where Ho Chi Minh attended school.

The NVA and ARVN fought in South Vietnam. The only fighting taking place in North Vietnam was between jet aircraft (the air war).
They were called peace negotiations; and the US simply wanted the North Vietnamese to pull their troops out of SOUTH Vietnam and quit trying to take it over.

The term "losing the war" only equates to the North Vietnamese Communists winning the war. The North defeated the South (whom the US defended and was allied with). North Vietnam didn't land in the United States and take America over.
The containment policy was that the US would fight against any attempt by existing communist countries to take over other countries and add them to the Soviet bloc. This was the reason for the Korean War (in which the North Korean effort to take over South Korea was successfully prevented) and the Vietnam War (in which the North Vietnamese effort to take over South Vietnam succeeded despite US efforts at containment).
Nixon had been elected to begin withdrawing US troops from Vietnam and to turn over more of the fighting to the South Vietnam government. In 1972, North Vietnam finally realized that the war was a stalemate. The two sides met and arranged a cease fire. In January of 1973 the Paris Accords went into effect. The US agreed to withdraw all its troops from Vietnam in 60 days. Congress had stopped funding the war effort. The North Vietnamese government agreed to release all prisoners, which they never did. Free elections were to be held in Vietnam. The President of South Vietnam considered the agreement between North Vietnam and the US as a sell out. But it allowed President Nixon to save face and bring the soldiers home. By 1975, after US troops had been pulled out of South Vietnam, the ARVN (Army of the Republic of South Vietnam) collapsed and the North Vietnamese moved into Saigon, ending the war and finalizing the take over of the South by the North.
