travel to France. In Gdynia, a group of Polish officials belatedly tried to persuade the Czechoslovaks to stay and join the Polish Air Force. A few, including another future RAF ace, Josef František, agreed to do so after tossing a coin. The remainder, including Kuttelwascher, stuck to their decision to leave Poland. On 30 July, they disembarked in the Port of Calais in France. French service Peacetime regulations did not allow the French Air Force to enlist people who were not French citizens. But the Czechoslovak Ambassador in Paris reached agreement with the French Government that Czechoslovak volunteers could join the French Foreign Legion for a five-year term, on the understanding that if war broke out they would be released to form a Czechoslovak army in exile. Kuttelwascher and his group joined the Foreign Legion and were posted to Sidi Bel Abbès in French Algeria for army training and to learn French. On 3 September 1939, France and the United Kingdom declared war on Germany. On 17 November, the French Government and Czechoslovak National Liberation Committee agreed that Czechoslovak airmen would be transferred from the Foreign Legion to the French Air Force pending the formation of a Czechoslovak air force. Kuttelwascher was one of about 100 who were sent to the fighter training base at Chartres Aerodrome, where he quickly learnt to fly the Morane-Saulnier M.S.406C.1 fighter. However, he was not transferred to a combat squadron until 17 May 1940, when he was assigned to Groupe de Chasse III/3 at Beauvais–Tillé. Four days later, GC III/3 moved to Cormeilles-en-Vexin, where it was re-equipped with the more modern Dewoitine D.520C.1 fighter. As German forces advanced in the Battle of France, GC III/3 retreated, first to Illiers-l'Évêque and then successively to Germinon, Chapelle-Vallon, Montargis, Grand Mallerey, Avord Air Base, and Perpignan-La Salanque. On 17 June, the UK Foreign Office sent a signal to its Ambassador to France, Sir Ronald Campbell, who had evacuated from Paris to Bordeaux, asking him to give the Czechoslovak General Sergej Ingr an order from President Beneš to evacuate all Czechoslovak personnel and as many aircraft as possible to England. However, in the chaos engulfing France, the order reached few if any Czechoslovak personnel, and Kuttelwascher and his comrades continued to serve with their French units. Kuttelwascher claimed that, while with the French Air Force, he destroyed or damaged several enemy aircraft. French records for that period are
