Manfred Albrecht Freiherr von Richthofen aka The Red Baron is better known as the rival of Snoopy from Peanuts. von Richtofen was possibly the top Ace pilot of World War I with over 80 air combat victories.

The Red Baron was killed in combat on April 21, 1918 possibly by a bullet fired from the ground – the identity of who fired the fatal bullet is still in dispute. He managed to land his plane and died as Australian soldiers reached him – his last words allegedly being “kaputt.”
The allies gave him a respectful full military funeral (video below:)
The body was returned to Germany after the war.
