Battery Way played a very limited role during the Philippines Campaign in the Spring of 1942, only becoming active in the last week of the battle. The battery had been out of service for several years, but three of the four mortars were returned to service with a crew from Battery E, 60th Coast Artillery (AA), recently evacuated from Bataan, by 28 April. These were fired for the first time on that day against Japanese positions on nearby Bataan. Its exposure to Japanese artillery, air attack, and its limited supply of high explosive shells greatly diminished its effectiveness. By the time of the Japanese landings on Corregidor island on 5–6 May 1942, only one mortar tube of Battery Way remained serviceable, the other two having been damaged beyond repair by Japanese artillery.
