That supply function created differences between the Army's supply and transportation organizations that were not resolved until early 1943 in a cooperative scheme. In particular the shortage of shipping had complicated all matters of supply with the ports making every attempt to use available space so that separate supply and transportation requirements were driving inefficiencies. WSA mandates to use available shipping space had driven the ports to fill every available space so that some material not actually required by the overseas command was loaded with the result that NYPOE had failed to heed supply instructions to cease automatic ammunition shipping to North Africa and "Ammunition and ration stocks in North Africa early in 1943 rose to embarrassingly high levels" due to consideration of those shipping requirements over supply requirements.
