Of further interest, Duffy, in his Army of Maria Theresa, gives the squadron frontage as 60 yards (72 paces) for 50 files in 3 ranks, but also suggests the regiment deployed in two lines of squadrons with a minimum of 50 paces between squadrons of the second line. If this is so, then the regiments were in a sense self supporting.
With our modified WRG 1685-1845 rule set, we do allow Hussar regiments to form two battalions due to their large size. After some consideration, we just may expand this rule to include Cuirassiers. Any readers acquainted with the WRG 1685-1845 , we also restricted the use of columns and squares and we do not allow mounted heavies to fire from the saddle during battle. There were however, isolated incidents of even Cuirassiers firing at the enemy while mounted (Battle of Reichenberg for one).
The photo illustrates some of Old Glory's humor. These are extra riders, two wounded (one still sporting a souvenier) and a third with pistol. I like that one.
