a wooden cannon, about 2 feet tall and 3 feet wide
Aim the cannon towards the nearest fortress. Gather men and start planning how to conquer it.
If the fortress belongs to (for example) a bunch of kids then invite the captain over for a drink in a house. Get 50 of your men and let them march around the house. Tell them to change clothes every now and then, to create an illusion which can't be misunderstood. Stare the captain in his eyes and tell him "You have no chance. We are 500 men marching outside this house, and we are here to conquer or die". Look away for a second, taste your beverage, look back and tell him this "I'll tell you what, I'll spare you and your men but only if leave your fortress within the next 24 hours".
or take the fort by force, I have an army, 10 000 strong
I crossed orcs with goblin men, they can travel in sunlight, crossing great distances with speed!
