The vast bulk of the ships we encounter in the course of cataloging the HRPE photographs are Liberty ships. Not entirely surprising, really, as there were 2,710 completed between 1941 and 1945, making them a large portion of the Army and Merchant Marine fleets. Some of the Liberties were converted to transport ships, and the reception was not entirely favorable. While the holds of a Liberty were just fine for crates of supplies or racks of bombs, fitting them up with bunks resulted in conditions like this:
The inscription on the back says these photos were taken to show the “crowded conditions”. For officers, conditions were slightly better, with bunks only three men high, and actual mattresses on springs.
