Due to a navigation error, the parachutists did not land where they had planned, and having lost a significant amount of material, the group members decided to split and operate on their own. One member, Ivan Kolařík, committed suicide on 1 April, 1942 after he was revealed, in order to protect his family members against reprisals.
First lieutenant Adolf Opálka, and Karel Čurda went to Prague and joined Operation Anthropoid, a group preparing assassination of Reinhard Heydrich. The assassination was successful, but Čurda revealed the hiding place of the assassins (Prague's Church of St. Cyril and St. Methodious) to the Gestapo. Following a fierce battle around the church, Opálka and others committed suicide rather than be caught.
