Before the operation, the guerrillas were allegedly responsible for harassing nearly a third of UN forces and conducting regular attacks on roads and railways used by them.

After the operation, the guerrilla forces were greatly weakened, although a resurgence remained a threat until the end of the war.

[2] In 1951, a large number of communist guerrilla groups, ranging in size from a few hundred to several thousand, were operating in territory supposedly controlled by UN forces and were attacking roads and railways, sniping at UN forces, and raising funds from local inhabitants.

Local anti-communist militias formed to fight back, sometimes engaging in savage reprisals against villages deemed to be supporting the guerrillas.

After the operation, communist guerrilla forces were greatly weakened, although thousands of Republic of Korea police had to remain in the area, supported by up to 11,000 local militia known as the Young Volunteers, in order to prevent the resurgence of the remaining guerrilla forces, who may have numbered about 3,000.
