Henryk Antoni Flame (or Flamme, nom de guerre "Grot" or "Bartek"; January 19, 1918 – December 1, 1947) was a corporal and pilot in the Polish Air Force, and a captain of the anti-Nazi, and anti-Communist resistance organization NSZ.

Back home, Flame began working as a machinist at the local rail year while at the same time establishing contacts with the anti-Nazi resistance.

At the end of 1943, due to the danger of an arrest by the Gestapo, together with his men he escaped to the forests where he organized an independent partisan group, which operated in the Beskid foothills.

[citation needed] The command of the National Armed Forces (NSZ) took notice of his actions and he received an invitation to join that organization.

Flame, acting on the orders of NSZ command, revealed himself to Soviet authorities and together with his men presented himself at their disposal.

However, at the same time, the group retained its conspiratorial structure (the ostensible purpose was to infiltrate the Communist authorities and bureaucracy with NSZ men).

[2] Realizing the orders of NSZ command he put his own men in charge of the police force and hired other anti-communists into the militia.

As before he escaped to the forests, assumed the nom-de-guerre "Bartek" and created a partisan unit - the NSZ Group of the 7th Region of Silesia and Cieszyn.

[3] At its height his unit numbered 300 men, all of whom had military uniforms and were well armed thanks to Flame's previous efforts as commandant of the MO.

[citation needed] In September 1946 in Operation Lawina, organized by a secret police mole in Flame's unit, the UB convinced him and many of his men that they could be transported to the American zone in Germany.

Individuals implicated in the annihilation of the Flames'-lead NSZ units were: Henryk Wendrowski (UB agent who penetrated its ranks), Roman Romkowski (Natan Grinszpan-Kikiel) who along with Marek Fink (Mark Finkienberg) devised and supervised the conduct of the Operation "Lawina".

After they were detained, they were ordered to take their clothes off, and then naked, they were individually lead to a 3 meter deep pit where they were murdered; everyone with a shot to the back of the head.

A secret death sentence was supposedly issued by the President of Poland Bolesław Bierut himself, who could not forgive the humiliation associated with a 400 strong NSZ unit staging a military parade in Wisła.
