 At the end of the war, despite the accomplishments of the other ports and sub-ports, the NYPOE remained the single port with the largest passenger and cargo numbers and only the San Francisco Port of Embarkation rivaling its role in the supported theater of war.The single issue driving nearly all the command's functions was availability and movement of shipping that was coordinated with the port but not under the sole control of the port.Troops and supplies had to be available to meet ship availability, the convoy cycle and sailing dates and adjustments made for events concerning ships from mechanical to weather and other demands.
