Thence the command went to the North Anna River, where they had a vigorous fight. They then moved to the crossing of the Pamunkey, threw up breastworks on the hills and kept in almost constant motion to some point; going to Cold Harbor and the Chickahominy, having moved June 1 to Bethesda Church. The 7th went to the James River and to Petersburg, erecting breastworks and preparing for participation in the work in the trenches there. For more than 30 days Colonel Robinson had not been able to remove his sword or his clothing and, harassed by slight wounds and worn out, there being a full line of officers, he resigned.
