"... At noon on June 12, 1942, Flight Lieutenant Alfred Kitchener "Ken" Gatward and his navigator Flight Sergeant Gilbert Fern flew at low level in a Beaufghter Mk Ic up the Champs-Élysées in Paris hoping to strafe a German parade that happened daily. As it turned out, the parade did not take place that day but they did shoot up the Ministère de la Marine which housed the German High Command Headquarters."
They dropped/draped the French tricolor over both the targets [Wiki: source]
