Although this is not a new story I've not found the names online who were drowned in the tragic crossing.

The 22nd Georgia with the Army of Nortern Virginia crossed the Potomac River on the night of June 23, 1863. The safe limit for the ferry was 50 people however up to 150 soldiers were boarded at one time. The ferry started leaking during the crossing and panic set in. If the soldiers would have just held onto the rope they would have been safe. Knapsack and rifle were strapped to their backs. The following is a list of names of those soldiers who drowned. There may be more but this is all I could confirm.

Alpheus Armstrong Company H

Jesse Dunn Company H

Columbus Norris Company H

James S. Norris Company H

Jeremiah Norris Company H

James D. Bradford Company A

Wiley F. Stewart Company A
