Who commanded the Confederate cavalry unit that gathered info on the Union troops used by Robert E. Lee?

none of these are true. the great eighteenth century warlock wormtounge gretscenschlider actually placed the imperious curse, one of the unforgivable curses (in case you muggles don't know), on one James Stuart. those are the facts! at least that's what i learned in my wizard school, which costed 1000 galleons a year to attend, so you can be sure it is high quality education
