I periodically refresh my memory regarding capturing maximum resource depots for different castles (based on a save from the Siberia-2013 competition). So, even with the ideal repetition of moves according to the excellent guide by Ikhtiandr, for the Swamp, in 1-2 cases out of 10, vampires will wait until the 3rd round and then fly to where they are not welcome. With non-ideal moves, the guide simply doesn't work.
