Draiss agreed in general, but wanted to make one addition. "How about a strike about an hour before dawn? If these hobgoblins and what not follow standard military protocol, they might change guards at dawn. If we strike just before dawn, then we can wipe out the current guards, and then destroy the second wave when they come in to relieve the last group. Even if they are not changing guards, the current shift would be tired and bored, and hopefully not paying attention."
