Army of Georgia
The Savannah campaign was launched on November 15 and concluded with the capture and occupation of Savannah on December 21, 1864 (36 days). There were 25 days of actual marching. Slocum's army traversed approximately 300 miles (480 km). Slocum's Army of Georgia moved, on average, 12 to 15 miles per day and passed through 31 counties in Georgia. The Union column traversed 15 major creeks, streams and rivers that required pontoon bridges. During the march, Slocum's troops employed individuals who were newly freed from slavery as pontoon builders and road-building detachments. The average distance of each crossing was 230 feet. Between Sherman's two armies, pioneers were required to build over 100 miles of corduroy roads. Weather was relatively clear, as it only rained on two days.
