Adam was shot down and killed on 15 November 1917 near Langemarck in his Albatros D.V. He was fighting enemy aircraft from both
No. 29 Squadron RFC and
No. 45 Squadron RFC; Captain
Kenneth Barbour Montgomery of No.45 Squadron,
Royal Flying Corps was the apparent victor. By the time of his death, Adam had already won the
Iron Cross First Class and the
Military Merit Order of Bavaria. However, posthumous awards continued. On 2 February 1918, Adam received the Knight's Cross with Swords of the
Royal House Order of Hohenzollern. On 20 May 1919, Bavaria's highest military decoration, the
Military Order of Max Joseph (
Militär-Max-Joseph-Orden), was posthumously bestowed on him, with effect from 28 July 1917. On that date, as deputy
Staffelführer of
Jasta 6, while his
Staffelführer chased one bomber, Adam had attacked and broken up the rest of a formation of enemy bombers, and continued the pursuit despite damage to his own aircraft, until his squadron had destroyed the enemy formation. For a commoner, award of the Military Order of Max Joseph carried with it a patent of non-hereditary nobility signified by the title "
Ritter von", and Hans Adam posthumously became Hans Ritter von Adam. Hans Ritter von Adam was interred in the
Waldfriedhof in
Munich, Germany. ==Decorations==
