As the progressively more elaborate fortifications of enemy civilizations make Trebuchets less and less effective at breaking through, dire necessity spurs on a new invention. Utilizing the miraculous recent developments in gunpowder, Renaissance engineers devised what essentially amounts to an oversized musket, designed to hurl massive metal balls with incredible speed against those pesky, now-obsolete walls.
Thanks to its enormous firepower, the Bombard has little trouble blasting through the defenses of Renaissance-era cities and their districts. Becoming available right after the Musketman, the pair are excellent in tandem with one another, as the swift Musketman can provide support for the ponderous Bombard on the battlefield. A small formation of Bombards positioned on hills or flat land within firing range of a city will easily demolish its defenses, leaving it ripe for the taking. Its decent defensive strength is an additional perk.

The oldest representation of a bombard – a muzzle-loading, smoothbore proto-mortar that was used to throw stone balls against fortifications during sieges – was found in China; the 12th Century AD Buddhist cave-sculpture depicts a demon firing one. In the Western world, English monarchs were certainly using them in the 14th Century, for Edward III had some at Crécy in 1346 and Henry V captured Harfleur using bombards in 1415. But with the largest weighing several tons and all notably inaccurate, bombards were not practical for field operations, soon enough being replaced by cannon; emplaced bombards, however, remained in use for centuries, usually protecting ports and sea passages. Among the last and largest, the Dardanelles Gun built by Munir Ali in 1464 weighted in at 16.8 tons and helped protect the straits for the Ottomans for a long, long time (being fired for the last time at a British fleet in 1807).
