Carlo the dog, mascot of the regiment

              One of the Pennsylvania regiments on leaving Philadelphia took with it a large black dog of Mongrel breed, who afterwards made himself conspicuous in the regimt, [regiment,] and by his inteligence [sic] and tact soon became known to a larger portion of the Army of the Potomac. This was one of the first fully equipped cavalry regiments that left Phila[delphia] and on its march down Broad street it naturally attracted considerable attention and by the time it reached the station at Broad and Prime [streets] the crowd was immence. [sic] Here it was that the regimental dog first reported for duty. From the very first he appeared intensely interested in all that was going on and when the train was ready to start he managed to get aboard and from that time he took the greatest interest in all movements of the troops. During the winter of 1861 and 1862 while the regiment was in camp preparing for the spring campaign the dog was one of its busiest members, always in attendance at drill and dress parade and frequently showing his approval or disapproval barking and jumping around in a nervous manner. [B]y spring "Carlo" had become familier [sic] with every member of the regiment and had attached himself to one of the companies but was always ready for duty with any portion of the regiment: When in the spring of 1862 the army under the command of Genl McClellan [General George B. McClellan (1826-1885)] made its move on Manassas, Carlo was on hand and proved himself very efficient in his particular arm of the service. On the failure of that movement and the return of the army to the vacinity [sic] of Washington preparitory [sic] to embarking for the Peninsula, Carlo remained faithful to his country's flag and accompanied his friends to Fortress Monroe, and was an active participater in all the battles[,] skirmishes
