The Weapon Every Army Tried to Erase — Cannon, 1450

In 1450, French cannon erased English Normandy in months, and every stone castle in Europe became obsolete overnight. Then a shape answered. The two French brothers Jean and Gaspard Bureau broke roughly sixty fortresses in about a year and killed the most famous English soldier alive at Castillon in 1453. Then, behind a breached wall at Pisa in 1500, desperate citizens improvised the earthen retirata — and Italian engineers turned it into the angled bastion, a geometry that held off the greatest empires on earth for four hundred years. This is the story of the fortress design every army tried to erase. ⏱ CHAPTERS 0:00 — The walls that failed in seventeen days 2:27 — The Bureau brothers and sixty broken fortresses 2:33 — The afternoon a cannon killed England's best soldier 12:17 — The blind spot at the foot of every round tower 17:26 — Pisa, 1500: what the citizens built overnight 18:29 — The retirata that broke the assault 18:56 — Machiavelli inspects the earthen wall 22:41 — Ostend: three years, one hundred thousand lives 32:02 — Fort Pulaski: the shape retired in a day and a half If this one earned your time, a like helps more people find it and subscribing means you'll be here when the next file opens. ⚠️ DISCLAIMER This video is for educational and historical purposes only.
