Among the Union troops caught by the tightening Confederate attack were the veteran 5th New York Infantry and the inexperienced 146th New York Infantry. The Confederates made no distinction between veteran and green troops, and both regiments, across the turnpike ahead and across the run to the left, had great difficulty escaping. Some soldiers fought their way out, while others were captured in large numbers. As retreating Federal regiments, harassed by Southern artillery fire, reached the hill to the right, they found relief in the arrival of the fresh Union division of Gen. Winfield Scott Hancock, which had advanced to cover George Sykes's withdrawal. After Sykes was clear, Hancock withdrew to Chancellorsville. Men of the 5th New York Infantry, known for their brightly colored Zouave uniforms, fought their final battle there because their enlistments expired only days later. Col. Kenner Garrard commanded the 146th New York Infantry from the summer of 1862 through the Battle of Gettysburg in July 1863.
