How Overconfidence Killed 1,329 Men - by myIQ

Added: 2026-05-28

[00:00:00]1,329 soldiers slaughtered in a single afternoon because one British commander refused to believe savages could outsmart him.

[00:00:10]January [music] 22nd, 1879, Isandlwana, South Africa.

[00:00:17]Lord Chelmsford receives reports [music] 20,000 Zulu warriors hiding in a nearby ravine.

[00:00:23]He laughs it off. They're uncivilized, no real threat.

[00:00:27]He splits his army, leaves the main camp unfortified, no defensive circle, no scouts.

[00:00:34]The Zulus attack at noon with their famous horns [music] of the buffalo formation.

[00:00:39]British soldiers rush for ammunition, but it's locked [music] in heavy wooden crates.

[00:00:44]They need screwdrivers, specific screwdrivers. Men face spears with empty rifles [music] and pocket knives.

[00:00:51]By sunset, 1,329 dead.

[00:00:56]This is overconfidence bias. When you believe you're superior, you stop preparing, and preparation is what keeps you alive.
