Career
Gallwitz originally flew a Roland Doctorate.III for artillery cooperation units on the Russian Front, shooting down two observation balloons with FA 37, before a brief assignment to Jasta 29. On 24 August 1917, he joined Jasta Boelcke. He scored three times in October.
The last one, on the 27th, was over Arthur Rhys-Davids.
He started over again in 1918, scoring five more times, including bringing down British aces Robert Kirby Kirkman and John Herbert Hedley. Gallwitz finished out his tally of ten on 21 April 1918, and crashed soon thereafter.
Once he recuperated from his injuries, he was assigned to Inspekteur der Flieger. He later was a professor for agricultural machinery at the university of Göttingen, where he taught from 1936 to 1965.
