Nic,
Not the coat you were looking for, but a good reference.

SUGAR PLANTER [WEST BATON ROUGE, LA], December 28, 1861, p. 2, c. 1

That Coat!—We are under many obligations to our gallant young friend, Lieut. B. Frank Babie, of the Continental Guards, 11th Regiment, L. V., for a splendid overcoat taken from a defunct Yankee upon the battlefield of Belmont. Mr. Yankee was leaving the field at a 2:40 pace, or perhaps a little faster, when Frank seized a gun from a soldier and fired, the effect of which was a slight interference with Mr. Yankee's locomotion. The coat was taken from him and now it adorns the dignified person of this graceful editor. The coat is valuable as a relic, and doubly valuable in cold weather. When we have worn it out we intend to have it cut up into smaller overcoats for the little Sugar Planters now two in number.
