Observe the keep’s guard shifts, then deploy a skirmish unit to create a diversion at the gate. While the guards are distracted, the main force moves in under the cover of dawn, exploiting the low‑visibility corridor. Keep the numbers tight, no one should see more than necessary. The key is to outmaneuver, not outnumber. Good luck, but remember – a well‑planned move always beats a lucky one.

Nice plan. Just make sure the skirmish doesn’t draw more fire than you can handle. Keep it tight, and the keep will fall like a chessboard piece. Good luck.
