T. H. Brooks, of Brig. Gen. William F. "Baldy" Smith's division. Attempting to hold the flank south of the Williamsburg Road, the Vermonters charged into the woods and were met with murderous fire, suffering more casualties of any brigade on the field that day. The brigade as a whole took 439 casualties; the 5th Vermont regiment, commanded by Lt. Col. Lewis A. Grant, lost nearly half of its men, 209 of 428. Aftermath The battle was a stalemate at the cost of about 1,500 casualties on both sides, plus 2,500 previously-wounded Union soldiers who were left to be captured when their field hospital was evacuated. Jackson eventually crossed the river by about 2:30 a.m. on June 30, but it was too late to crush the Union Army, as Lee had hoped. Most of the Army of the Potomac crossed White Oak Swamp Creek unmolested by noon on June 30. Lee reprimanded Magruder in a dispatch: "I regret much that you have made so little progress today in the pursuit of the enemy. In order to reap the fruits of our victory that pursuit should be most vigorous.... We must lose no more time or he will escape us entirely." However, the fault for the lost opportunity must be shared equally with the poor staff work at Lee's own headquarters and a less-than-aggressive performance by Jackson. The Seven Days continued with the much larger Battle of Glendale and the Battle of White Oak Swamp on June 30.
