BFME Patch 2.22 Without Building a Unit - Mission 10 - Helm's Deep

Rules of the run:
1. No producing units whatsoever. This includes trebuchets and timed units from call-ins, including Aragorn's level 10 ability.
2. Game is set to hardest difficulty.
I made quite a few mistakes. Notably I lost Theoden and the Rohirrim when I got a bit too greedy. As you can see this difficulty is quite forgiving so I was still able to beat the level. 7 units of elves and 2 units of rohirrim survived, which is alright considering the best possible outcome is 10 units of elves and 3 rohirrim, the peasants and yeomen are mostly useless. I had to grind a bit to get Gandalf to level 9, but that makes Minas Tirith a lot easier. The next time the elves and Rohirrim wil be useful is at the Black Gate.

It's over Anakin, I have the high ground. Impressive stuff!
