Fort Stotsenburg, during the World War II era, was the location of the Philippine Department's 26th Cavalry Regiment, 86th Field Artillery Regiment, and 88th Field Artillery Regiment; along with the Philippine Division's 23rd and 24th Field Artillery Regiments. Also based here were the 12th Ordnance Company and a platoon of the 12th Quartermaster Regiment.
Fort Stotsenburg is situated at Barrio Sapang Bato in Angeles City and is approximately 80 km north of Manila. This was one of the locations where, under the National Defense Act of 1935, field artillery training was conducted. It was named after Colonel John M. Stotsenburg, a Captain of the Sixth U.S. Cavalry, and a Colonel of the First Nebraska Volunteers who was killed while leading his regiment in action near Quingua, Bulacan, the Philippines on April 23, 1899.
c.1917, Fort Stotsenburg was home to the 1st Philippine Artillery Regiment.
By October 1902, American forces had established more or less permanent quarters near the Angeles railroad station in an area of the town known as Talimundoc (now the barangay of Lourdes Sur). The rumor is that cavalry foragers had come across a fertile plain further to the north and that sweet grass was abundant in this area. The U.S. cavalry forces had encountered problems caused by the fact that their horses became sick and often died after eating Philippine "sawgrass."
