Before he could move, however, Grant was faced with the problem of disengaging from Lee's army. Not only were the armies closely situated, Grant's first had to withdraw north over the North Anna, during which it would be very vulnerable to attack. Grant decided on a series of deceptive measures to disguise his intentions. On May 26, he sent a cavalry division under Brig. Gen. James H. Wilson to Little River, probing the western end of the Confederate line, while at the same time men from the cavalry divisions of Brig. Gens. Alfred T. A. Torbert and David McM. Gregg were sent to the Little Page Bridge and Taylor's Ford on the Pamunkey, 10 miles upriver from Grant's intended crossing points. Lee, who was still in his tent suffering from the diarrhea that had incapacitated him during the North Anna battle, was fooled by Grant's actions and assumed that the Union general would be moving west for the first time in the campaign.
