Now as you all know the Civil War was a time of great innovation. Much progress was made in the medical and military fields. One of the more interesting stories of progress came during the battle of Fredericksburg. The thing I am talking about is the first amphibious landing of troops under fire. The Federal troops were ordered to board one of the pontoon bridges, cross the Rappahannock and snuff out the fire from William Barksdales Mississippi sharpshooters. It took much effort and the loss of many men, but the Federals made it over, landed on the river bank. Once their feet hit the ground they had made history. Not only had they taken part in a significant battle in the Civil War they had also made military history by being the first troops to make an amphibious landing under enemy fire.
