CANNON POWERFUL...

Cannon operation required specialised crew and gunners, who were first enlisted by the Spanish in the 14th century.[1] The nature of cannon operation often depended on the size of the cannon and whether they were breech-loading or muzzle-loading. English cannon of the late 14th century became mobile, while the largest cannon (such as the heavy siege cannon of the Ottoman Turks or the Jaivana cannon of India) required huge crews to transport and operate them.

As the "giant gun" trend disappeared in Europe, in favour of lighter, more manoeuvrable pieces in larger numbers, and cannon operating crews became smaller, heralding the early use of true field artillery. While the medieval Dardanelles Gun had required 200 men just to operate it, 18th-century English cannon required only a dozen men, including two gunners, while during the Napoleonic Wars five gunners were used
