WWII
Despite a high enlistment rate in the U.S. Army, African Americans were not treated equally. At parades, church services, in transportation and canteens the races were kept separate. A quota of only 48 nurses was set for African-American women, and the women were segregated from white nurses and white soldiers for much of the war. Eventually more black nurses enlisted. They were assigned to care for black soldiers. Black nurses were integrated into everyday life with their white colleagues. The first African-American woman sworn into the Navy Nurse Corps was Phyllis Mae Dailey, a Columbia University student from New York. She was the first of only four African-American women to serve as a Navy nurse during World War II.

Eventually Roosevelt withdrew his plan after fighting for it for a long time, but he gave up.
