Operation Deckhouse IV was an operation conducted by the Special Landing Force (SLF) Battalion Landing Team (BLT) of 1st Battalion, 26th Marine Regiment in the eastern Demilitarized Zone (DMZ), lasting from 15 to 18 September 1966.[1]

Prelude

U.S. intelligence indicated that a PAVN was moving into the area between Con Thien and the DMZ and the 1st Battalion, 4th Marines conducted a reconnaissance in force of the area from 7-13 September making intermittent contact with PAVN units identified as coming from the 90th Regiment of the PAVN 324B Division. LG Lew Walt planned Operation Deckhouse IV as just a larger reconnaissance in force of the same area using the SLF floating reserve.[1]

One company of BLT 1/26 Marines would be landed by amphibious assault craft north of the Cửa Việt River and 2km south of the DMZ and then sweep 6 miles (9.7 km) west to meet up with the rest of the battalion which would be landed by HMM-363 helicopters west of Highway 1.[1]
