On board the USS Lehigh, Charleston Harbor, 16 November 1863, during the hazardous task of freeing the Lehigh, which had been grounded, and was under heavy enemy fire from Fort Moultrie. After several previous attempts had been made, Williams succeeded in passing in a small boat from the Lehigh to the Nahant with a line bent on a hawser. This courageous action while under severe enemy fire enabled the Lehigh to be freed from her helpless position.
