Mary Lincoln Extra Credit Questions

[RJNorton]

In 1864 Mary Lincoln visited a soldier who was in the hospital. She visited him twice, and brought him flowers the first time and wrote to his mother the second time (while she was sitting next to him). She did not tell the soldier who she was, and he only found out after he recovered and was back home and saw the letter his mother had received.

What was the name of this soldier?
