How can I stop being so bad at attacking in siege battles?

I've save scummed this same siege battle about 4 times now and I cant quite crack it.

So the defending garrison is about 900 strong and my army is 1500. I make the siege towers and the battering ram.

Because apparently non of the armies I summon have their own packed lunch I can only carry around 15 days of food for them. Due to this I cant stave the enemy town out. For the same reason, I dont have sufficient time to break the walls.

So the battle itself always pans out the same. The enemies catapults destroy the battering ram before it reaches the gate. The siege tower reaches the wall and the infantry go up it all goes well. Eventually though unless i hide behind a wall somewhere I will get hit by a medieval chris Kyle and then I get to watch my army do the same thing over and over and over.

'Infantry charges'

They almost break through

'Infantry is retreating'

Half of them are shot in the back by defending crossbows

This happens till the entire army is gone

I feel like I'm missing something to be honest

Am I meant to spend the entire siege battle hiding so that the lobotomised AI can't take over and turn the army into sausage meat?

Is there a way to store more food in your army? I am already over my inventory capacity with grain.

Any tips would be appreciated
