There were at least 16 men of the 10th Louisiana Infantry that joined the 3rd Maryland Cavalry. Thomas Walter Brooks and Michael Dan Jones provide an extensive breakdown in their book "Lee's Foreign Legion - A History of the 10th Louisiana Infantry".

The fact that the 3rd Maryland Cavalry was assigned to New Orleans, could have been an important point in the decision making process of these men. In September 1863, could it have been known or rumoured that such an assignment was in their future?
