For cavalry I'd say carbines of long rifles the infantry was using.
He was a member of a cavalry battalion.
A cavalry leader is the Troop Commander; a captain's position (slot).
The cavalry is on horses, while the infantry are on foot.

Generally awful. The British heavies (notably the Scots Greys) charged with great elan and effect, but failed to stop before reaching the Frnch guns, and were cut off by the French lancers and pretty much wiped out. The French cavalry charged the Allied centre when Marshal Ney thought the British infantry were retreating - they weren't; they were just backing off about fifty yards to get on the reverse slope of the hill out of sight of the French guns. When the cavalry arrived, the British formed squares which were impregnable to cavalry attack, and Ney never thought to order up guns and infantry to help them. Result - failure and frustration. The light cavalry on both sides, on the other hand, performed creditably. The Polish lancers finished off the British heavies; the British lights under Vivian and Vandeleur supported the infantry by flank attacks on French columns; and the Prussian lights pursued the retreating French and completed the rout.
The French had arrived to Cambodia in the Year of 1863 =)
