North Anna River to Cold Harbor

“As Grant began to disentangle his army from the lines at Spotsylvania and march by his left flank, he hoped to use some of his men to pin down Lee’s army while marching others to the North Anna River and the railroad line at Hanover Junction about 25 miles away.
If he could accomplish that by beating Lee’s army to those spots, he would have captured one of Lee’s most natural supply lines while depriving the Army of Northern Virginia from using the North Anna River as a defensive line.”*
