How many Union troops were killed at the Fort Pillow Massacre?

During the Fort Pillow Massacre, which occurred on April 12, 1864, between 277 and 295 Union troops were killed. The majority of these soldiers were African American.12

While it is difficult to distinguish exactly how many of these deaths occurred during the heat of battle versus those who were killed while attempting to surrender, modern historians overwhelmingly agree that a massacre took place, as evidenced by the fact that twice as many Union soldiers were killed as were wounded—an inverse ratio for typical Civil War engagements.2
