Monday, May 16, 1864
This morning at 5:00 A.M. the Confederates attacked the Union line in a dense, enveloping fog. Over the next four hours the Thirteenth New Hampshire drove back three Confederate charges and held their portion of the line. Around 9:00 A.M. the Thirteenth withdrew from their position to form a new line of battle with their brigade, where the Thirteenth New Hampshire repelled a Confederate charge. The major fighting for the day ceased by 2:30 P.M. Company E of the Thirteenth New Hampshire returned to their regiment encamped at Bermuda Hundred around 10:30 P.M. after a hard day of fighting on the skirmish line. Although the Thirteenth New Hampshire performed well this day, many other units suffered heavily by wounding or capture during the early morning attacks in the fog.1
