Second Battle of Memphis

The Second Battle of Memphis was a battle of the American Civil War occurring on August 21, 1864, in Shelby County, Tennessee. At 4:00 a.m. on August 21, 1864, Maj. Gen. Nathan Bedford Forrest made a daring raid on Union-held Memphis, Tennessee, but it was not an attempt to capture the city, which was occupied by 6,000 Federal troops. The raid had three objectives: to capture three Union generals posted there; to release Southern prisoners from Irving Block Prison; and to cause the recall of Union forces from Northern Mississippi. Striking northwestward for Memphis with 2,000 cavalry, Forrest lost about a quarter of his strength because of exhausted horses. Surprise was essential. Taking advantage of a thick dawn fog and claiming to be a Union patrol returning with prisoners, the Confederates eliminated the sentries.
