The Dardanelles Gun was cast in bronze in 1464 by Munir Ali with a weight of 16.8 t and a length of 518 cm, being capable of firing stone balls of up to 63 cm diameter. The powder chamber and the barrel are connected by the way of a screw+ mechanism, allowing easier transport of the unwieldy device.
Such super-sized bombards had been employed in Western Europe siege warfare since the beginning of the 15th century, and were introduced to the Ottoman army in 1453 by the gunfounder Orban+ (from Brasov+, Kingdom of Hungary+) on the occasion of the Siege of Constantinople+.Schmidtchen (1977b), p. 226 Ali's piece is assumed to have followed closely the outline of these guns.
Along with a number of other huge cannons, the Dardanelles Gun was still present for duty more than 350 years later in 1807, when a Royal Navy+ force appeared and commenced the Dardanelles Operation+. Turkish forces loaded the ancient relics with propellant+ and projectile+s, then fired them at the British ships. The British squadron suffered 28 dead through this bombardment.
