Meade was severely criticized for not counterattacking Lee after the third day of battle. The next day Meade sent out skirmishers, but did not attack. Lee had his army hold its position on Seminary Ridge all day on July 4. The more than 10,000 wounded men would be moved by wagon train to Williamsport and cross the Potomac to Virginia. The rest of Lee's army followed on the night of July 4–5, screened by Jeb Stuart's cavalry. The next day, on discovering the Confederates had left the battlefield, the Union army cautiously followed. At the Battle of Falling Waters, Lee's army was waiting for the flooded Potomac River to go down so his army could cross. Meade's forces caught up with them there but the battle had no clear victor. The Battle of Falling Waters was the last battle in the Gettysburg Campaign.
