Defensive Cannons

Description:

The Defence Cannon (守銃) was employed to repel the enemy’s siege assault. It was relatively diminutive in comparison to other cannons. As a result, it functioned as a close-range weapon that served to accurately attack the troops from the top of the defensive wall when they were attacking the wall closely.

Description:

The Hog Cannon (彖銃) was named because its muzzle and barrel were wide compared to other cannons. It was typically employed in defensive. When the enemy was approaching, different types of ammunition could be loaded into its wide barrel. This cannon could then be so powerful at close range.
