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 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.
