On 4 April 1943, African American soldiers formed a line for drinking water in a bivouac area in New Orleans, Louisiana. The National WWII Museum identifies them as members of the 493rd Port Battalion and preserves the scene in an official U.S. Army Signal Corps photograph. The record directly establishes the unit, place, date, and the ordered wait for water.

The photograph does not tell us the total length of the line, the waiting time, the capacity of the water point, or the day's temperature. Nor can one image establish conditions throughout the Army. Keeping those limits visible matters. What it does show is that drinking water in this camp was not simply available on demand; it was a provision received in sequence within military routine.

Large wars are often narrated through ships, ports, and campaigns. Their daily operation also depended on repeated acts of supply. This photograph preserves the work of a port battalion through one of the most basic of those acts: waiting one's turn for water.
