Some of the refugees never made it to Sweden; a few chose to commit suicide; some were captured by the Gestapo en route to their point of embarkation; some 23 were lost at sea when vessels of poor seaworthiness capsized; and still others were intercepted at sea by German patrol boats. Danish harbor police and civil police often cooperated with the rescue effort. During the early stages, the Gestapo was undermanned and the German army and navy were called in to reinforce the Gestapo in its effort to prevent transportation taking place; but by and large the German military troops proved less than enthusiastic in the operation and frequently turned a blind eye to escapees. The local Germans in command, for their own political calculations and through their own inactivity, may have actually facilitated the escape.
