I recently did a bit of reseach into the papers of Surgeon Edward Lloyd Howard, PACS and shared these with Noah at Harper's Ferry a couple weeks ago. He suggested I transcribe them and make them available here. This is the first of them, a circular from Medical Director Hunter McGuire regarding badges for the Ambulance Corps.
Hd Qrs 2nd Army Corps
Med : Department
April 13, 1863
I send you to day 150 Badges for the Ambulance Corps of your command. You will distribute them to the Regimental & Battalion Surgeons and instruct them when a battle or an affair with the enemy becomes imminent to issue them to the Ambulance Drivers and men detailed to remove the wounded from the field. With the number sent you will be able to give to each Regiment or Battalion 15 Badges for the detailed men (varying number however according to the size of the Battalion) leaving 50 to be used by the ambulance drivers and to provide for losses. They should be worn served to the front part of the crown of the hat, and if practicable have upon them some mark by which the Ambulance Corps of your command can be distinguished from others of this command.
When the Battle is over and the detailed men sent back to their Regiments & Battalions, the Regimental Medical Officers should collect these badges from the men and keep them until occasion again calls for their use.
As the Lieut Genl Commanding will issue orders prohibiting, all officers & man not wearing these badges from assisting in the removal of the wounded, you will enjoin upon the Med: Officers of your command the importance of providing for each one of the Ambulance Corps one of these badges.
I am Dr.
