Janoušek was then to command a Czechoslovak Air Force training centre, which was to be built at Cognac in western France. It never materialised. On 10 May Germany invaded the Netherlands, Belgium and France. As French armed forces were collapsing, on 18 June Janoušek and a large group of Czechoslovak airmen left Bordeaux aboard a small Dutch ship, the "Karanan", which reached Falmouth in England on 21 June. The next day France capitulated to Germany.
