This Week in the Civil War - #852
On Sunday, June 12, 1864 Grant ordered the 100,000 man Army of the Potomac to move from Cold Harbor. In the darkness of the night four corps were sent toward the James River and an additional corps was dispatched by water down the Pamukey River and up the James. When Lee learned of the Federals’ movements, he shifted his army southward, assuming Grant’s next assault against Richmond would come from the north. In fact, Grant’s forces deceived Lee. By the morning of the 15th all Union infantry and four batteries of artillery had crossed the James to the south side, and William Smith’s corps which moved by water up the James arrived a Bermuda Hundred, reinforcing Benjamin Butler’s Union forces for an immediate attack against Petersburg, south of Richmond.
