Hannibal Strikes at Trasimene

Rome walks into history's deadliest ambush

On the misty shores of Lake Trasimene in central Italy, the Carthaginian general Hannibal sprang one of the most devastating ambushes in military history on a Roman army under Consul Gaius Flaminius. Hidden in the hills above the lake, Hannibal's forces trapped the Romans between the water and the mountains, killing or capturing nearly the entire army of twenty-five thousand. The disaster at Trasimene was Rome's worst defeat since the Battle of the Allia -- and worse was still to come at Cannae.

China Declares War

The Qing Empire challenges the world's great powers

At the height of the Boxer Rebellion, the Qing dynasty formally declared war on the United States, Britain, Germany, France, and Japan -- an extraordinary act of defiance by a weakened empire against the combined might of the industrialized world. The declaration, driven by Empress Dowager Cixi's support for the Boxer militants, led to an eight-nation military intervention that captured Beijing and imposed devastating reparations on China, accelerating the dynasty's final collapse.
