Secret Activities of the Polish Underground

  The Home Army maintained constant communications with the Polish
  government-in-exile in London, using secret radio transmissions.  Messages
  and microfilm were sent by courriers travelling through Nazi-occupied
  territory on their way to London.   The Underground was able to organize the
  clandestine landing of Allied aircraft on three separate occasions - an
  accomplishment that is quite astounding considering that the Germans were
  expert at scrutinizing airspace and communications.  On the last of these three
  flights, one of the passengers was the Captain of the Home Army, Jerzy
  Chmielewski, who successfully transported the plans, and precious parts of
  Germany's V-s1and V-2 missiles to London.

  Underground activities were so effective in its organization that not only were they  widespread throughout Poland,
  but had members operating inside Germany, and the Soviet Union.  Counterintelligence was given the mission to
  protect the Underground from being infiltrated by the enemy.  The Underground, or Home Army (AK) successfully
  intercepted a shipment of 100 million zlotys from the Germans.  Poles carried out sabotage virtually everywhere
  in particular in Gdansk and Berlin.

  All plans  for sabotage and diversionary tactics were organized by the committee for " Underground Struggle "
  ( Kierownictwo Talki Podziemnej ).  Sabotage involved clandestine operations resulting in the damage or
  destruction of any sector of the German war machine and its administration.

  Factories manufacturing armaments and planes, as
  well as trucks, cars, tanks, railways, ships, bridges,
  and so on, were all targets for sabotage.

  Diversionary tactics were carried out on Germany's
  military and on the transport of their supplies.

  Colonel Emil Fieldorf (Code Name: Nil) headed the Command of Diversion (KEDYW).  His brigade was known
  as the Gray Ranks ( Szare Szeregi ), and consisted of 20 officers, 43 officers in training, 64  non-commissioned
  officers, 344 privates, 79 women, and 113 auxiliary.  These were a secret group of the  Polish Scouting  Associa-
  tion.  There were many such units but most  noteworthy was one of three platoons of the  AK which dealt with
  armed sabotage.   The ODB3, led by Lt. K. Pogorzelski ( Code Name: Rygiel ) consisted of about 50 men,
  including a woman's support unit.  Among the unit were 3 officers, 20 cadet-officers, and 10 NCO's, all well-armed
  and supplied with explosives.  They captured several German vehicles, which were subsequently used in
  numerous sabotage missions, to great success.

  The KEDYW was stationed mostly in larger cities, however there were large units deployed in the countryside.
  These units ranged in size from platoons to brigades, to divisions.  One such division was the 27th Volhynian
  Division posted to the Wilno district.  They were responsible for inflicting severe damages and losses to the
  Germans.  Their activity greatly assisted the Allies on the front lines.   Diversionary propaganda was conducted to
  demoralize German soldiers.  Frequent messages were relayed taunting the Germans with threats that they
  would  be defeated and utterly humiliated.  Numerous secret bulletins, periodicals and newspapers were printed. 

  The ZWZ , one of several Polish underground troops, obtained information that the Germans were secretly
  planning to invade the Soviet Union in June 1941,  and immediately sent a message to the Polish government
  in London warning them of that outcome.  In fact the Germans attacked on June 22.   However, the ZWZ
  encountered enormous difficulties in infiltrating the western part of Poland as it had been absorbed into the
  German Reich.  Similarly, there were difficulties in eastern region where the Soviets had established themselves.
  The Underground could not infiltrate the south-eastern region  ( around Lwow ) because the area was
  under surveillance by armies of Russian spies.  The greatest success was made in the north-east near
  Vilno and Bialystock, and in the central Poland, that is the  " General Gouvernement ".

  But their success changed drastically when the Germans attached Russia in 1942.  The Russians spent as
  much time fighting off the Gemans as they did the Poles.  The SS as well as the Soviets recruited Ukrainian
  nationalists to kill the Poles resulting in one of the most infamous m assacres in modern history.  Thousands
  of Poles were brutally slaughtered.

  The Intelligence Service of the AK regularly monitored the activity of the German army and air force, and provided
  information on every discovery to the Allies.   The most valuable information relayed to London was the
  discovery of the German rocket manufacturing plant at Peenemunde.  It led to a successful air raid by the RAF
  on August 17 - 18, 1943,  destroying the entire plant.

  Diversionary tactics included misinformation, that is the planting of information designed to confuse and create
  disillusionment among the German soldiers.

  As plans were being made for a future uprising, women were permitted to join the ranks of the AK, and fight
  during the uprising.

  In April of 1942, while Germans and Soviets were battling on Russian soil, the Supreme Council of the AK
  ordered that tactics be switched from acts of sabotage to that of armed diversions. Particular attention was given
  to plans for the destruction of warehouses, bridges, troop trains,  airfields, telephone and radio installations.
  During this period several hundred actions took place.  They began their guerilla operations in the same year.
  Of the many incursions, one in particular was impressive.  On December 31, 1942, the Germans began the
  removal of the Polish population in the area of Zamosc for the purpose of replacing them with German settlers.
  The partisans, assembled in the forests near Zamosc, and Krasnobrod, initiated many attacks which lasted
  until mid-February 1943.  At that time, the Germans had to abandon their colonization plans. Its police, army
  battalions, tanks and warplanes all had to retreat  as a result of attacks from the Polish Underground.  There
  were other large-scale counter-offenses by the Underground, in operations in the forests between Radum and
  Kielce (Central Poland), in addition to the northeast region between Vilno and Nowogrodek.
