McGrew. American Legion, Post #8 Los Angeles, CA. On this date in history in 1918, Quentin Roosevelt, the youngest and favored son of former President Theodore Roosevelt, was shot down and killed. He was engaged in a dogfight against either an Albatros D.V or a German Fokker D.VII, two of Germany’s penultimate fighter planes at the end of the war.At the time, Quentin Roosevelt was just 21 years of age and serving as a Second Lieutenant and pilot with the US Army Air Service. He was assigned with the 95th Aero Squadron of the 1st Pursuit Group. That day, he was flying a French-built Nieuport 28 aircraft. The Nieuport 28 was a nimble, fast machine, but it was outclassed by the new generation of German aircraft, particularly the Fokker D.VII, which is widely viewed the finest aircraft of the war. Item 5 is a rare and unique photo of Quentin Rosevelts Grave during WWI.
