text: Later years Nine days after the combat with von Richthofen, Brown was admitted to hospital with influenza and nervous exhaustion. In June, he was posted to No. 2 School of Air Fighting at Marske Aerodrome, as an instructor. He was involved in a bad air crash on 15 July, and spent five months in hospital.
  Brown left the RAF in 1919 and returned to Canada where he took up work as an accountant at a small town grocery store and later moved to Toronto to work at Imperial Varnish and Color Company until he retired in 1934. He also founded a small airline in 1928, General Airways Limited in Amos, Quebec and in same year married Edythe Moneypenny. Brown worked for a while as editor of Canadian Aviation. When the Second World War broke out, he attempted to enlist in the Royal Canadian Air Force, but was refused. He instead entered politics, losing an election for the Ontario legislature in 1943. The Browns moved to Stouffville in 1939 and in 1943 purchased a dairy farm at Bethesda Road and Warden Avenue near Stouffville, Ontario (now part of the property of Rolling Hills Golf Club). Brown was inducted into the Canadian Aviation Hall of Fame in 2015.
