Crump officially remains the last surviving veteran of the Confederate States Army.

Assigned to Company A, Crump saw action at the Battle of Hatcher's Run, and participated in the siege of Petersburg before witnessing General Robert E. Lee's surrender at Appomattox Court House to Union General Ulysses S. Grant.

Returning home to rural Alabama, Crump soon relocated to Lincoln, in nearby Talladega County.

The United Confederate Veterans awarded Crump the honorary title of colonel in its organization.

In 1950, he met with 98-year-old "General" James Moore, who was recognized as the only other Confederate veteran remaining in Alabama.
