From the marker for the regiment on Chinn Ridge:

The enemy in our front, moving in concert with those on our flank, came out of the woods – their line masking and overlapping our own. The whole left of our brigade poured into them a murderous volley. The combat grew fierce indeed. But the contest was not long. On came the flanking column. We stood until the enemy had nearly gained our rear, and had opened fire upon our flank. Then we retired. -Samuel B. Hurst, Regimental Historian
