1812 Napoleon began the retreat from Moscow. What defeated him were General Typhus and General Hubris. General Winter deliver the coup de grace.

1954 Britain ceded Suez canal to Egypt by treaty and withdrew the 80,000 troops it had there. In a last spasm of colonialism two years later Great Britain went back into the Canal in one the most catastrophic foreign policy blunders of the ages. The irony is that the blunder came from the hand of one of the most experienced diplomats England ever produced.
