The 7 most notorious traitors in military history

There are a lot of hated people in military history and no one is more hated than a turncoat. Even the troops on a traitor’s new side will never trust them entirely — after all, they turned their back on their own country for personal gain.  How trustworthy can they be?

This list details the most notorious, most gut-wrenching, most fatal backstabs in military history. These are direct betrayals of historical figures, in alphabetical order.

There are no abstract judgment calls (like naming Judas Iscariot), no political statements (like calling out Nixon for extending the Vietnam War), and no traitors for good causes — Rommel tried to kill Hitler, but that’s hardly “notorious.”

7. Emilio Aguinaldo

Aguinaldo fought many foes to liberate the Philippines and its people, including the Spanish and the Americans. Once captured (he was actually betrayed by his own men) and released, he would wear black to mourn lost Philippine independence. When the Japanese brutally occupied the island, you’d think he’d go right back to fighting invaders killing Filipinos.

You’d be wrong.

He made radio addresses and speeches, imploring the Americans and Filipinos to surrender on Bataan in the hopes of getting the Japanese to make him President of their puppet government. The people ignored him.

When the U.S. retook the islands, he was jailed as a collaborator. Although remembered as the first President of the Philippines, “Japanese collaborator” is a huge stain on his anti-colonialist résumé.

6. Benedict Arnold

The name Americans love to hate. His name is so synonymous with the word “traitor” in the U.S., calling someone a “Benedict Arnold” can still cause fists to fly over 200 years later. Arnold wasn’t a bad general — his skills were critical to early American victories, especially at Saratoga. However, Arnold felt passed over and used.

Instead of pressing on and waiting for his day to come, he offered to surrender West Point to the British in exchange for money and a general’s commission in the British Army. The British didn’t get West Point, though, because Arnold’s plan was discovered and he escaped to British lines.

5. Ephialtes of Trachis

This is the guy who the historian Herodotus says betrayed the Greeks at Thermopylae. It was there the outnumbered Greeks formed a bottleneck in the pass between the Malian Gulf and the “impassable and precipitous” mountain to the west.

Herodotus’ account says Ephialtes showed the much-larger Persian army a “single-wheel track” that ran behind the Greek lines. Once surrounded, the Greeks were, of course, slaughtered.
