For most of that period, the regiment was stationed in Brightwood, now a neighborhood of Washington but, at the time, outside of the urban area of the city.

The conditions at Fort Stevens were favorable as compared to many winter camps during the Civil War and the regiment had a very low rate of sickness.

Here, Union forces under the command of Major General George B. McClellan gathered in preparation for an advance on the Confederate capital of Richmond via the Virginia Peninsula.

[1] After the failure of the Peninsular Campaign, the 7th Massachusetts withdrew with the rest of the Army of the Potomac to Fortress Monroe.
