Relations between Lee and Crawford were never good, so Lord personally handled most of the communication with Eisenhower's Supreme Headquarters Allied Expeditionary Force (SHAEF). He also dealt with most of the complaints coming from the field, and starting in January 1945, also submitted weekly reports to ASF. American logistics in the Northern France campaign suffered from supply shortages in the aftermath of the breakout from Normandy and the Allied advance from Paris to the Rhine, and resulted in clashes between Lord and Brigadier General Raymond G. Moses, the assistant chief of staff for logistics (G-4) of the 12th Army Group. Lord offered statistics to show that COMZ deliveries were exceeding the amounts requisitioned, but Moses argued that this was the result of the armies restricting their requisitions. They needed of supplies per division slice, but were receiving only , and could not be comforted with statistics.
