'Freston' was an Allied undercover liaison mission to the resistance forces in German-occupied Poland (26/27 December 1944 onward).

A six-man team led by Colonel Marko Hudson was flown from Bari in southern Italy and parachuted into Poland, some 50 miles (80 km) to the north of Kraków. The team was overrun in the middle of January 1945 by the advancing Soviet forces, and its members arrested and imprisoned to be released only on 12 February after the Yalta conference had decided that Poland lay in the Soviet sphere of influence.
