The Army's second experiment with integration came in part from the need for infantry replacements during the Allied advance across Western Europe in the summer and fall of 1944.[2-100] The Ground Force Replacement Command had been for some time converting soldiers from service units to infantry, and even as the Germans launched their counterattack in the Ardennes the command was drawing up plans to release thousands of soldiers in Lt. Gen. John C. H. Lee's Communications Zone and train them as infantrymen. These plans left the large reservoir of black manpower in the theater untapped until General Lee suggested that General Dwight D. Eisenhower permit black service troops to volunteer for infantry training and eventual employment as individual replacements. General Eisenhower agreed, and on 26 December Lee issued a call to the black troops for volunteers to share "the privilege of joining our veteran units at the front to deliver the knockout blow." The call was limited to privates in the upper four categories of the Army General Classification Test who had had some infantry training. If noncommissioned officers wanted to apply, they had to accept a reduction in grade. Although patronizing in tone, the plan was a bold departure from War Department policy: "It is planned to assign you without regard to color or race to the units where assistance is most needed, and give you the opportunity of fighting shoulder to shoulder to bring about victory.... Your relatives and friends everywhere have been urging that you be granted this privilege."[2-101] [Footnote 2-100: For a detailed discussion, see Lee, _Employment of Negro Troops_, Chapter XXII.] [Footnote 2-101: Ltr, Lt Gen John C. H. Lee to Commanders of Colored Troops, ComZ, 26 Dec 44, sub: Volunteers for Training and Assignment as Reinforcements, AG 322X353XSGS.] The revolutionary nature of General Lee's plan was not lost on (p. 052) Supreme Headquarters, Allied Expeditionary Force. Arguing that the circular promising integrated service would embarrass the Army, Lt. Gen. Walter Bedell Smith, the chief of staff, recommended that General Eisenhower warn the War Department that civil rights spokesmen might seize on this example to demand wider integration. To avoid future moves that might compromise Army policy, Smith wanted permission to review any Communications Zone statements on Negroes before they were released.
