After 1941
In 1941 several members of TIGR were condemned for espionage and terrorism at the Second Trieste trial; four of them (Viktor Bobek, Ivan Ivančič, Simon Kos and Ivan Vadnal) were executed in Villa Opicina near Trieste the same year, jointly with the Communist activist Pinko Tomažič. By the time of the Axis invasion of Yugoslavia in April 1941, most of the organization was already dismantled by both Italian and Nazi German secret police and most of its prominent members either sent to concentration camps, killed or exiled.
During World War II, many of its members joined the partisan resistance, although the organization itself was not invited to join the Liberation Front of the Slovenian People.
