20 Famous Surrenders That Turned Into Massacres

After Julius Caesar defeated the Gauls at Alesia, thousands of them surrendered in the hope of receiving clemency. Instead, many were enslaved or massacred to serve as a warning to the others. The scale of these reprisals meant that this victory seemed less like a conclusion and more like a true declaration.

As Roman forces invaded the city, many residents surrendered or were captured. A large number of them were executed or enslaved, even though they were no longer offering any resistance. The fall of Jerusalem was as much a matter of destruction as it was of conquest.

When Mongol forces captured Baghdad, the surrender did little to protect the population. Massacres ensued, devastating one of the most important cities of the time. These events wiped out entire communities and destroyed the existing political order.
