Scorched earth
A scorched-earth policy is a military strategy that aims to destroy anything that might be useful to the enemy while it is advancing through or withdrawing from a location. Any assets that could be used by the enemy may be targeted, for example food sources, water supplies, transportation, communications, industrial resources, and even the locale's people themselves.
Battle of Boykin's Mill
Union troops pursued the fleeing Southerners unsuccessfully, and the mill was burned to the ground according to Major General William T. Sherman's "Scorched Earth" policy. The engagement proved to be the bloodiest battle of the campaign for the 54th which had had the highest casualty rate of the operation. However, the two opposing units (Potter's and the Kentuckians) continued to skirmish through April 19 at Dinkin's Mill where they fought the last major conflict of the Eastern Theater. The preliminary cessation of hostilities was announced to both sides two days later though Confederate General Johnston did not officially surrender until 26 April.
