What was the dirtiest trick ever pulled in the history of war?

During the Second World War, German forces would rig crooked wall paintings to explode,

when straightened, with hopes that it would kill Allied officers when they came in to set up command posts.

The logic being that Private Joe Blow clearing the building, looking for enemies,

isn't going to care or even notice of a painting as a skew.

But General Robert Important Guy who sets up his new command post in the building and is in his office for hours probably would notice.

The Germans also strung piano wire across roads to take out anyone riding by in a Jeep.

Yep, my Gramps told me a story about this.

After he was wounded for his third time, they made him a courier. He was on a motorcycle,

and because of these piano wires, he'd always ride hunched over. He lost a small piece of

scalp instead of his head when he drove underneath one of these wires. When Timur the

lame was about to attack the city of

Sivas, he promised the 3,000 Christian Armenian Sipahis that he wouldn't shed any of their blood if they

surrendered. So they surrendered, and true to his word, he had them all buried alive. In World War I,

the Allies became used to the smell of chemical weapons and would put their gas masks on quickly. The Germans changed their tactics and then would use nearly odourless, stomach emptying chemicals that would absorb quickly into the lungs first. Then, once the soldiers were all spewing up and couldn't keep their gas masks on, they would fire the main

artillery barrage containing the lethal chemicals.

According to some records in the art of war, it's considered a good strategy to corner

your men and have the enemy attempt to wipe them out, because when the only means of escape

or survival is through the enemy, then your own men will fight to the death.

The actor George Sanders found out that his friend David Niven was very chummy with Winston Churchill during the war.

He asked Niven to give the Prime Minister a note detailing his idea for a new bomb that the RAF could drop on German cities.

It would be exactly the same as all the old
