After Yellow Tavern, Sheridan led his troops southward towards Richmond on May 11, carefully feeling his way through the abandoned outer defensive works. He kept up his movement down the Brook Pike, not realizing that he was boxing himself into a potential trap. Sheridan found himself only two and half miles from his objective, but saw that the intermediate defenses in his front swarmed with enemy troops. His left flank was against the swollen Chickahominy, and Confederate cavalry threatened his rear, hoping to capture the Union force.
