Prelude
Operation Fillmore was a continuation of the harvest security operations of Operation Harrison.[1]
Operation
The 1st Battalion, 327th Infantry Regiment was retained as a reserve force at Tuy Hoa Air Base, while the 2/327th Infantry and the 2nd Battalion, 502nd Infantry Regiment patrolled the rice-growing plains and the western foothills.[1]
In early April, 2/502nd Infantry was rotated to Tuy Hoa Air Base and 1/327th and 2/327th began a block and sweep operation in the mountains northwest of Tuy Hòa. On 7 April a company from 1/327th engaged an entrenched company-sized force, killing 28 defenders.[1]
Given that the PAVN had apparently withdrawn from the Tuy Hòa Valley, on 9 April 1/327th and 2/502nd were redeployed, leaving only the 2/327th Infantry to continue operations.[1]: 194
Aftermath
Operation Fillmore officially concluded on 21 July, the US claimed PAVN losses were 134 killed and 35 captured, U.S. losses were 8 killed.[1]: 194
