Battery Grubbs is located in the west center of Corregidor Island to defend Manila Bay. The battery faces to the northwest 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.

Wartime History
On April 11, 1942 a Japanese aerial bomb hit the power plant at Battery Grubbs putting the battery out of service. Next, on April 16, 1942 a direct hit disabled the No. 2 gun and 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.
