During Heydrich's posting in Prague, a serious incident put him and Canaris in open conflict. Heydrich requested that Canaris put the "Abwehr" under SD and SS control. Canaris appeared to retreat and handled the situation diplomatically, but there was no immediate effect on the "Abwehr" for the time being. In fact, Canaris had established another two links with MI6—one via Zürich, and the other via Spain and Gibraltar. It is also possible that Vatican contacts provided a third route to his British counterparts.
