Does this idiot know nothing about warfare? The enemy is extremely well fortified and extremely well versed in naval combat and repeling enemy invasions from the waterfront, his men are utterly unfamiliar with naval combat nor invading from the waterfront, he has a roughly 0% chance of success, especially as he demands his men march without rest or preparation. You cannot win on morale alone, you need to understand strategy and logistics, and this commander seems to know neither. He should have just gone home with his tail between his legs because he's not cracking that defense with his inexperienced men. Lick his wounds, come back later with a more experienced force that has trained for this kind of operation.
