From John Hennessy:
After their rebuke at the Battle of Arby’s, the Union army recoiled long enough along the Warrenton Road for the Confederates in Falmouth to both prepare to leave and to burn the bridges in their wake. Soon after dawn, as the Union columns swept down the hill into Falmouth, the Confederates put their plan into action. The Falmouth Bridge went up in flames, as did the Chatham Bridge and the R,F&P bridge farther down. Fredericksburg had never seen such a day. Some white residents scattered, fearful of the looming Yankees. Some slaves rejoiced at the Yankees’ coming. And a few people ventured out to watch, including diarist Betty Herndon Maury, who left a vivid description of the destruction that day.

There were two or three rafts dodging in between the burning vessels, containing families coming over to this side with their negroes and horses.
Here are a couple of images that show some of the damage described by Mrs. Maury. The first shows the destroyed ships opposite city dock–drawn in May 1862.

This is the only known image that shows the destroyed Falmouth Bridge, burned by the Confederates on April 18. Lumber from the bridge was taken by Union engineer Washington Roebling, who in June built a wire suspension bridge on the abutments of the Chatham Bridge (we wrote about Roebling’s bridge here).
