Its first commanding officer arrived on November 21, 1941; on June 1, 1942, the depot received its first shipment—four cars of propellant charges. The first commercial vessel was loaded on September 7, 1944. By December 31, 1945, it had received more than 329 million pounds of ammunition and had shipped more than 208 million pounds.
The depot continued to operate between 1945 and 1950; plans to phase out operations as soon as the decreasing need for war materials allowed were postponed with US involvement in the Korean War in June 1950. In 1959, the depot was declared surplus, and the US Army Corps of Engineers took custody. In October 1964, it was sold to the Houston Channel Industrial Corp. for more than 10 million dollars.
