The lack of stevedores in combat zones was a huge issue for the Navy. Authorization for the formation of cargo handling CBs or "Special CBs" happened mid-September 1942. By wars end 41 Special CBs had been commissioned of which 15 were "colored". They were the first fully integrated units in the U.S. Navy. V-J Day brought the decommissioning of all of them. The Special CBs were forerunners of today's Navy Cargo Handling Battalions of the Navy Expeditionary Logistics Support Group (United States). The arrival of 15 colored Special CBs in Pearl Harbor made segregation an issue for the Navy. The 14th Naval District felt they deserved proper shelter with at least separate but equal barracks. Manana Barracks and Waiawa Gulch became the United States' largest colored military installation with over 4,000 Seabee stevedores housed there. It was the site of racial strife to the point that the camp was fenced in and placed under armed guard. The Seabees were trucked to and from the docks in cattle trucks. Two naval supply depots were located at Waiawa Gulch. At wars end 12,500 African Americans would serve in the Construction Battalions.
