After Christina left to harass the enemy, Anning commanded his Artillery to throw the cannons and ammunition carts to the front of the ambush zone, blocking the road perfectly.
Upon positioning, Anning personally loaded the last cannon, aiming it at the road surface.
Once fired, the cannonball would roll down the road, smashing everything it encountered.
The reason he didn't load Shotguns was that the pellets were small and had less kinetic energy, stopping after penetrating a few people.
Loading ordinary Solid Bullets, though they might not kill many at the cannon's mouth, would create a swath of casualties as they rolled down the road.
Most importantly, Shotguns could only harm the first few ranks of the enemy, whereas a Solid Cannonball rolling could penetrate through most of the formation.
Having people far in front die compared to those nearby cut in half has an incomparably devastating impact on morale.
Anning needed to win by crushing the enemy's morale.
