Battery Grubbs is located in the west central inland part of the Corregidor
Island defending Manila Bay. The battery faces a northwesterly direction, primarily to cover the approached to the North Channel, but was capable of covering the entire North Channel as far as Cabcaben on the Bataan Peninsula.
Built by the U. S. Army. Constructed between 1907 and 1911 at a cost of $212,391. Named Battery Grubbs in honor of 1st Lt. Haydon Y. Grubbs, US Army 6th Infantry, who was killed in action on October 1, 1899 near Tabuan, Philippines.
Battery Grubbs emplaced two 10" (254mm) Model 1895 guns on Model 1901 disappearing gun carriages capable of firing at a maximum range of 13,500 yards (7.7 miles) and with a 220° field of fire. The standard crew was 22 men per gun with a maximum rate of fire slightly better than two rounds per minute.
10" Model 1895 Cannon (No. 1)
Built by Watervliet Arsenal during 1903 serial number 25. Mounted on a disappearing gun carriage built by Watertown, NY during 1906, serial number 14. After installation, the Number 1 gun had suffered some mechanical failures and was never commissioned or manned during the war.
10" Model 1895 Cannon (No. 2)
Built by Watervliet Arsenal during 1903, serial number 22. Carriage built in Watertown, NY during 1910 serial number 16. Not manned at the start of the Pacific War. During early April 1942, personnel from Battery C of the 91st Coastal Artillery from Battery Morrison manned the Number 2 gun, placing it into action.
10" Model 1895 Cannon (Spare Gun Barrel)
Built by Watervliet Arsenal serial number 20, built in 1899.
On April 11, 1942 a Japanese aerial bomb hit the Battery Grubbs power plant, putting the battery out of service. Next, on April 16, 1942 a direct hit disabled the No. 2 gun and also destroyed the battery commander's station. Afterwards, the battery was abandoned.
Prior to the surrender of Corregidor, both guns were fired with the trunnion caps removed, causing them to jump out of their carriages causing damaging them.
The Japanese attempted to restore Battery Grubbs to a usable state, but before they could complete the work, the 1944-1945 American bombardment of Corregidor
Island further damaged Battery Grubbs and they abandoned the effort.
