In the afternoon of 20 May 1940, the Hurricane units based in northern France were ordered to abandon their bases on the continent and return to Great Britain. On the same day, "Bull" Halahan requested the repatriation of the pilots serving in 1 Squadron. During the previous 10 days, the unit had been the most successful of the campaign; it had claimed 63 victories for the loss of five pilots: two killed, one taken prisoner and two hospitalised. 1 Squadron was awarded ten DFCs and three DFMs during the "Blitzkrieg". On the evening of 21 May, the only Hurricanes still operational were those of the AASF that had been moved to bases around Troyes.
