The article quotes Andrew Gordon stating "It really is time to put away this enduring myth. To claim that Germany failed to invade in 1940 because of what was done by phenomenally brave and skilled young men of Fighter Command is hogwash. The Germans stayed away because while the Royal Navy existed they had not a hope in hell of capturing these islands. The Navy had ships in sufficient numbers to have overwhelmed any invasion fleet." On publication the article drew some attention, despite it not being a wholly original new thesis, having been first posited by Duncan Grinnell-Milne in his book Silent Victory (1940). From 2007 to 2009 Gordon was on loan to the United States Naval Academy from his position as Reader in Maritime History at the Joint Services Command and Staff College
