Beginning on December 10, 1864, Union and Confederate soldiers fought near Shaw’s Bridge and Shaw’s Dam as Union General William T. Sherman’s army moved toward Savannah. In bloody fighting, Confederates twice repulsed Union attempts to overwhelm the Confederate earthworks covering the causeway across the Savannah-Ogeechee Canal. On December 20, 1864, after the fall of Fort McAllister due south, the Confederates abandoned their defensive positions and retreated into the city, setting the stage for the surrender of Savannah two days later and marking the end of Sherman’s March to the Sea.
