Alfred Redl and Austria
If betrayal by numbers is anything to go buy, Austrian army officer Alfred Redl takes the cake. Before and during World War 1, Redl worked as a spy for the Russian military and sold secrets about the Austrian army. Redl leaked the Austrian invasion plan for Serbia, which Russia in turn sold to Serbia. He continued to double cross his countrymen by supplying the wrong information about Russia’s military strength and exposing Austrian agents to the enemy. The results were catastrophic for the Austrian army: his actions contributed to the deaths of half a million Austrians. Redl committed suicide after Austrian police discovered his betrayal.
Harold ‘Paul’ Cole and Britain
Harold Cole was the deputy commander of Scotland Yard during the end of the World War 2 and is considered one of the worst traitors of the war. He was responsible for divulging information to the Gestapo about the French resistance escape lines, which he had helped create. He also divulged information about the French resistance leaders to the Axis, resulting in the death of at least 150 people. He was shot dead after capture by French police in 1946.
Brutus and Caesar
The tyrannical rule of Roman emperor Julius Caesar came to a very sticky end when his own nephew, Marcus Junius Brutus, took part in the murder plot against him. Brutus joined the Roman senate during a time when the revolt against Caesar was reaching its peak. Despite remonstrations from his wife, Brutus accompanied a group of disgruntled senators who savagely attacked Caesar. Suffice to say, Caesar didn’t see it coming – particularly since the iconic line, “Et tu, Brutus?”, escaped his lips just before his demise. The whole sordid betrayal was also the subject of a little Shakespearean play you may have heard of.
