Many non-Britons served in the Royal Air Force during the Battle of Britain in July–October 1940, drawn from the British Empire and Commonwealth, neutral states, and from exiles from countries in German-occupied Europe. The largest contingents were provided by Poland, New Zealand, Canada and Czechoslovakia, though a total of 15 countries and colonial territories are represented between the two principle lists. While estimates of the number of foreign aircrew vary depending on documentation and definitions used, the two most authoritative sources cite between 564–596 foreign personnel, representing 19–20 percent of the RAF's active strength during the Battle.
