The memorial website to SSG Homero Martinez includes many private family photos of the 131 in Texas and Louisiana.
This gallery set shows the 131 FA Rgt at Camp Bowie and during the Louisiana Maneuvers.
The Regiment departed SFCA for Pearl Harbor in late NOV 1941 aboard the SS REPUBLIC. After a brief stop, they sailed west in a convoy escorted by the USS PENSACOLA. That convoy included the Belgian ship BLOEMFONTEIN which would carry them to Java in early 1942.
