Weapons Company History Early Years The battalion was first activated in 1925 at Naval Base San Diego, California. Since its initial inception in 1925, this unit has had several periods of activation. World War II On May 1, 1941, at Cavite, Philippine Islands became the First Separate Marine Battalion, Navy Yard, Cavite. Relocated during December 1941 to Corregidor, Philippine Islands. Redesignated January 1, 1942, to the Third Battalion, Fourth Marines, Corregidor, Philippine Island. The 4th Marine Regiment participated in the Battle of Corregidor from January to May 1942. The unit was ordered to surrender by Lieutenant General Jonathan Wainwright on May 6, 1942, an order with which Colonel Samuel L. Howard, the commanding officer of the 4th Marines, agreed. Colonel Curtis, the regimental executive officer, ordered Captain Robert B. Moore to take the regimental colors outside and burn them rather than allow them to fall into enemy hands. Once the order was carried out, Colonel Howard wept and said, "My God, and I had to be the first Marine officer ever to surrender a regiment." After this 4th Marines temporarily ceased to exist. On February 1, 1944, four Marine Raider battalions were amalgamated into a re-established 4th Marine Regiment, bearing the name and honors of the original 4th Regiment lost in the Philippines in 1942. The 1st, 4th, and 3rd Raider Battalions became respectively the 1st, 2nd, and 3rd Battalions, 4th Marines. The 2nd Raider Battalion became the regimental weapons company. Forming part of the 1st Provisional Marine Brigade and later 6th Marine Division, the 4th Marines fought in the battles of Guam and Okinawa. Vietnam War On April
