Wing Commander Mark Henry Brown, DFC & Bar (9 October 1911 – 12 November 1941) was a Canadian-born flying ace who served with the Royal Air Force (RAF) during the Second World War.

Mark Henry Brown, who was nicknamed 'Hilly', was born on 9 October 1911 in Portage la Prairie in Canada.

On 23 November, Brown was credited with a share in the destruction of a Dornier Do 17 medium bomber near Le Cateau.

The pace of operations began to pick up the following month and Brown destroyed a Messerschmitt Bf 109 fighter over Thionville on 20 April.

1 Squadron's return to the United Kingdom, it was rested and brought back up to strength, coming operational again in late July.

[3] At this time, Brown was awarded the Distinguished Flying Cross (DFC) for "gallantry and devotion to duty in the execution of air operations".

By this time, much of its flying personnel were Czechs and Poles who had escaped to the United Kingdom following the German occupation of their countries.

[6] During this time, he was awarded a Bar to his DFC, on 23 May, the published citation reading: This officer has commanded the squadron with outstanding success.

His splendid leadership and dauntless spirit have been largely instrumental in maintaining a high standard of efficiency throughout the squadron.In July Brown was promoted to wing commander and transferred to No.

[6] In October 1941 Brown was posted to the Mediterranean theatre of the war, where he was to lead the fighter wing at Ta Kali, on the island of Malta.

A little while later, during a raid on Malta, an Italian aircraft dropped a message that Brown had been buried with full military honours.

[9] In January 1943, he was posthumously awarded the Czechoslovak Military Cross by the Provisional Government of that country "in recognition of valuable services rendered in connection with the war".

[10] Military aviation historians Christopher Shores and Clive Williams note that many of Brown's claims in the Battle of France were reconstructed after the evacuation of No.

Shores and Williams credit Brown with shooting down fifteen German aircraft, and shared in the destruction of four more.
