Vamp,
I got him from a shop on one of my visits to Gettysburg, he came in a set of 4 x 54mm metals with no manufacturers markings on the base just "Gettysburg Soldiers".
I used a little artistic licence to fit the story line and made them Virginians where actually the figure is depicting a soldier and the battalion mascot of the 1st Maryland (Confederate) but history has not recorded the dogs name.
Don Troiani has painted a great picture called "Band of Brothers" showing the 1st Maryland's charge against the Federal Breastworks at Culp's Hill on the morning of the Third of July some hours before Pickett's famous charge on Cemetery Ridge and you can clearly see the mascot way out in front almost as if leading the advance. The charge was repelled and the battalion was almost annihilated including the dog.
However Vamp as you're a mascot lover best not read on..............Federal General Thomas L. Kane kept a diary of his Gettysburg experiences and after the battle of Culp's Hill that morning he walked across the battlefield and heard a weak whimpering, he noticed the dog and knelt beside him. His diary entry stated
"....as I knelt by the bloodied body of the dog he licked my hand even though he was perfectly riddled with minies"
