What happened to Black Union soldiers who tried to surrender at Fort Pillow?

During the Fort Pillow Massacre on April 12, 1864, many African American Union soldiers who attempted to surrender were killed by Confederate troops under the command of Maj. Gen. Nathan Bedford Forrest.12

While the fighting was characterized by chaotic, close-quarters combat and a breakdown of command, evidence confirms that in numerous instances, Black soldiers were gunned down after throwing down their arms in an attempt to surrender. The brutality of the event is highlighted by the casualty statistics: roughly 60 percent of the white troops present were taken prisoner, whereas only 20 percent of the Black soldiers were captured. In total, between 277 and 295 Union troops were killed, the majority of whom were African American. This slaughter became a rallying point for Black soldiers, who adopted "Remember Fort Pillow!" as their battle cry.132
