From 1943 onwards Switzerland stopped American and British aircraft, mainly bombers, overflying Switzerland on nine occasions, six times by Swiss air force fighters and nine by flak. 36 Allied airmen were killed. On 1 October 1943 the first American bomber was shot down near Bad Ragaz, with only three men surviving. The officers were interned in Davos and the airmen in Adelboden. The representative of the US military intelligence group based in Bern, Barnwell Legge (a US military attaché to Switzerland), instructed the soldiers not to flee but most of them thought it to be a diplomatic joke and gave no regard to his request.
