well i cant really remember that much off the top of my head.. but basically i believe that Vietnamisation led to the american/south vietnamese defeat... given that it placed the power in the hands of the SV, it meant that they ended up losing more battles, having increased casualties etc etc because despite the fact the US had provided them with weapons etc, they were poorly trained and inefficient
i recommend the textbook "conflict in indochina" by ian sutherland if you can find it anywhere-- it's better than War Without End
in
Conflict in Indochina, it has something which might be of interest to you--
(pg. 115)
Problems With Vietnamisation
- The South Vietnamese Army was increased to over a million men. This meant that there were twice as many soldiers to drain the economy and live off the people.
- It increased the opportunities for officers to take part in corruption. The example was set at the top, with Vice President Nguyen Cao Ky playing a central role in the drug trade. Making money and playing politics occupied most of the general's time.
- The US became closely tied to the Thieu regime. This small group lacked political support and relied on the Army to stay in power.
- The ARVN became reliant on US weapons (M-16's, Hueys, tanks). The ARVN were not familiar with these weapons and they were not weapons that had been successful for the US in the war.
- The military initiative was clearly with the Communists. The North Vietnamese played an increasing role and the Communist Army became much more regular than a guerilla force.
i hope that helped you a bit.
