It’s not though. It’s Napoleon.
Battle of Austerlitz, 1805.
According to accounts, when his marshals were eager to attack, Napoleon advised patience, reportedly saying, “Then, gentlemen, let us wait a little; when your enemy is executing a movement in error, never interrupt him.”
The earliest documented version of this advice appears in Archibald Alison’s 1836 work History of Europe, which recounts Napoleon saying, “In that case let us wait twenty minutes; when the enemy is making a false movement we must take good care not to interrupt him.”
