The losses are simply Mounted Swordsmen (all of them in worst case scenario).
About Ali Baba, the Young Woodcutter, initially, I had only C2 / C8 / C12 as camps for Mary Christmas and 2MoS 95ArM 103MoM seemed the best common denominator (I know 100ArM 100MoM will work almost always, but there's a small risk of losses, that's why I prefer to add 2 MS to protect Armored Marksmen).
Some combat simulators show XP from single camps).
