Cannon

“When diplomacy fails, we speak in iron and fire.”

The Cannon represents the maturation of gunpowder siege technology, replacing the crude hurling mechanisms of earlier ages with precision-forged metal barrels that fire heavy iron shot with terrifying force. No city wall can withstand sustained bombardment from a battery of well-served Cannons.

Strategy

The Cannon is the siege weapon that makes conquest practical in the Renaissance and Industrial Eras. With 16 base Attack and a +50% siege bonus, Cannons effectively hit cities with 24 Attack – enough to reduce even well-defended cities to rubble in a few turns. Any serious offensive campaign should include at least two Cannons to batter down defences before your Musketmen storm the walls.

Like all siege weapons, Cannons are fragile and slow. With only 6 Defence, a Cannon caught by cavalry or aggressive infantry will be destroyed in a single engagement. Protect your Cannons at all costs – they are expensive, slow to replace, and indispensable. Position them behind your infantry line, ideally on elevated terrain where they can fire over friendlies. Upgrade your veteran Catapults to Cannons as soon as Metallurgy is researched to carry forward their hard-earned experience and promotions.

Historical Background

The first effective siege cannons appeared in the 15th century, and their impact was immediate and dramatic. In 1453, the Ottoman Sultan Mehmed II deployed enormous bombards – including the legendary “Basilica” cannon, reportedly over 8 metres long – to breach the walls of Constantinople. Walls that had resisted sieges for over a thousand years crumbled in weeks, ending the Byzantine Empire and announcing the age of gunpowder fortification.

The arms race between cannon and fortification drove some of the Renaissance’s greatest architectural innovations. The medieval high wall, which presented a perfect target for cannonballs, was replaced by the trace italienne – low, thick, star-shaped fortifications with angled bastions designed to deflect shot and eliminate dead zones. Military engineers like Vauban elevated fortress design to an art form, but the fundamental equation remained unchanged: given enough guns and ammunition, any fortification could eventually be reduced.
