Here's another obscure photograph from my archive which was taken at Fort Shafter, T.H. in 1921. But this time it's not the Hawaiian Division but a cadre unit for the formation of the Philippine Division.
Members of the 1st Battalion, 23rd Field Artillery Regiment on their way to the Philippines.
The 23rd Field Artillery Battalion was a field artillery battalion of the regular Army, constituted as a US-manned unit in 1921, but redesignated as a Philippine Scouts unit in 1930. Constituted 16 August 1921 in the Regular Army as the 1st Battalion, 23d Field Artillery. Redesignated on 1 January 1930 as 1st Battalion 23d Field Artillery (Philippine Scouts).
In 1921, the U.S. Army created the Philippine Division, composed primarily of Philippine Scouts. The division’s major combat units were 43d Infantry Regiment (PS), 45th Infantry Regiment (PS), 57th Infantry Regiment (PS), 23d Field Artillery Regiment (PS), and 24th Field Artillery Regiment (PS). In 1922, 26th Cavalry Regiment (PS) was formed as a separate unit.
