Buoyed by the recent victory in the Binh Gia campaign and the support of their major allies, North Vietnamese leaders began preparing a strategy to defeat South Vietnamese and United States military forces. Lê Duẩn, Secretary of the Communist Party, believed that the South Vietnamese regime was able to survive because they still had a strong army to rely upon. Therefore, to win the war and reunite the country, the South Vietnamese military had to be destroyed completely. Lê Duẩn believed the Communist forces must destroy three or four of South Vietnam's nine regular army divisions in a series of large battles, and pin down the eleven elite battalions of the South Vietnamese strategic reserve. Thus, North Vietnamese leaders decided to launch a summer offensive with the objective of defeating the ARVN by drawing them into battle repeatedly with numerous, geographically dispersed attacks.
