Introduction
You live in a time of unprecedented institutional stability, but historical crises can suddenly strip away your laws, your government, and your safety. You might wonder how a nation survives when its territory is conquered, its leaders flee, and foreign powers systematically dismantle its entire social fabric.
A clandestine courier reveals how the Polish Underground built a comprehensive shadow state and risked everything to warn the free world of the Holocaust.
Jan Karski recounts how Poland absorbed the simultaneous shock of German and Soviet invasions in 1939. You will discover how ordinary citizens built a secret state with its own administration, judiciary, and military. You will trace the dangerous paths of underground couriers who carried vital intelligence across enemy borders.
The book answers several crucial questions about this hidden era:
- How did a shattered society organize a functioning underground government?
- What did the Gestapo do to captured resistance members?
- How did the Polish resistance infiltrate the Warsaw Ghetto and transit camps?
- Why did the free world fail to act on firsthand reports of the Holocaust?
1. Defeat and Double Occupation
On August 23, 1939, you receive a secret mobilization order via a red paper slip delivered by a policeman. You must report to your artillery detachment within four hours. Most reservists view this limited mobilization as a mere riposte to the Nazi war of nerves. You assume Hitler is bluffing and that England and France will deter a full-scale conflict.
The sudden German and Soviet invasions partitioned Poland and doomed the military, plunging the nation into total war and forcing survivors into immediate underground resistance.
Without warning or formal declaration, the Luftwaffe bombs the camp at Oświęcim on September 1, 1939, at 5:00 a.m. Modern German tanks cross the frontier, and local residents of German descent begin firing from windows as part of the Fifth Column. Your reserve battery marches toward the railroad amid three hours of incredible destruction and disorganization. Fifteen days of chaotic retreat follow before you reach Tarnopol on September 18.
Here, Red Army forces cross from the east following the Ribbentrop-Molotov pact. Commanders use megaphones to urge Polish soldiers to surrender voluntarily and join forces against the Germans. An overwhelmed non-commissioned officer commits suicide by shooting himself in the brain right before the disarmament. You and two thousand other men are marched off as prisoners.
The Outbreak of War
Captured officers are crammed into freight cars and transported deep into Russian territory for four days and four nights. Sixty men are packed into each freight car. You arrive at a camp where four hundred officers are assigned to each of the ten large wooden barns converted into barracks. Guards assign you arduous manual labor like woodcutting, treating officers as idle lords who need to learn how to work. You volunteer to clean heavy iron kettles in exchange for food remnants, securing extra rations for six weeks.
Soviet Capture and Escape
You exploit the terms of the German-Soviet prisoner exchange pact to orchestrate an identity swap and escape Soviet captivity. You ally with three resilient men, including a mechanic named Franek Maciąg, forming a corporative status that pools resources. Franek sews one hundred zloty into his underwear, and you hide two hundred zloty in your shoe. You trade uniforms with a Ukrainian peasant named Paradysz in the forest and assume the status of a private.
You must follow these steps to escape Soviet captivity:
- Find a private who does not intend to be exchanged and persuade him to trade uniforms.
- Execute the uniform trade while out chopping wood in the forest.
- Return to the barracks separately so guards do not notice the absence during the headcount.
- Approach a guard and request a transfer based on birth origin in incorporated territories.
You transfer to German control at Przemyśl after waiting five hours in an unsheltered field. German guards display arrogant contempt and immediate brutality. You enter the Radom distribution camp, where inmates receive twenty grams of stale bread daily. You witness six men riddled by bullets for approaching the barbed wire.
Fearing permanent subjugation, you plan a train escape during a forty-eight hour journey in a cattle car measuring fifty feet long, ten feet wide, and eight feet high. You deliver an impassioned speech to convince eight soldiers to join you and secure the cooperation of the rest.
You execute the train escape through a specific method:
- Wait for nightfall when the train approaches forests and rain reduces the visibility of outside guards.
- Gain the consent or passive compliance of the other men in the freight car to avoid betrayal or obstruction.
- Form parties of about eight men at two of the windows.
- Have three men hold a fourth by his shoulders, knees, and feet to half-push and half-throw him out of the window.
You trudge through the rain for three hours to reach a peasant cottage. An old peasant and his wife feed you hot milk and black bread, provide old trousers and jackets, and let you sleep on a lumpy mattress. You reach Warsaw after eleven weeks of war, finding the city devastated by Blitzkrieg and starvation policies. Your sister stares fixedly at a photograph of her husband Aleksander, who was arrested, tortured, and executed by the Gestapo three weeks prior.
2. The Structure of the Underground State
The Polish Underground unified disparate factions into a massive clandestine state complete with administration, justice, secret press, and military branches.
Unlike resistance movements in other occupied countries, the Polish Underground created a comprehensive clandestine state structure that operated across multiple civilian and administrative sectors. Norman Davies and other historians note that this underground network operated successfully right under the noses of the Nazi occupation forces. Effective resistance work requires abandoning flashy spy tropes in favor of absolute inconspicuousness and prosaic methods.
- Be inconspicuous.
- Melt into the landscape.
- Seem humdrum and ordinary.
Jan Karski utilized false documents, codenames, and disguises, but emphasized that survival depended on basic, unglamorous precautions. Women often make superior conspiratorial workers compared to men due to their heightened perception of danger and lack of ego. A young female courier handled the delivery of underground newspapers to dozens of locations daily. Residents of occupied Poland lived under two completely incompatible and hostile systems of justice and law. Resistance operatives were equipped with cyanide capsules, and suspected collaborators were routinely eliminated to protect the network.
Unification and the Four Pillars
In the late 1939 adolescent stage of the Polish Underground, the movement was fragmented into numerous isolated, haphazard, and short-lived resistance groups. Groups such as The Avengers, The Gory Hand, and God's Judgment operated with heterogeneous aims before stable political parties and military remnants began the process of unification. The chaotic Underground was stabilized through external and internal unification principles, bridging domestic resistance with the Polish government-in-exile and coalescing political parties. Main political movements including the National Party, the Peasant Party, the Socialist Party, and the Christian Labor Party created a united front with the government-in-exile.
The Underground movement consolidated into an institutionalized Secret State designed to maintain continuity and resist the occupiers.
The Underground established a coalition of four major political parties and integrated a civilian administration led by a Chief Delegate of the government, ensuring that the Polish state continued functioning in secret. Karski carried back the Doctrine of the Polish Underground from France in April 1940, acknowledging the unification of all resistance groups. The coalition united the Peasant, Socialist, Christian Labor, and National parties, all of which shared a commitment to parliamentary democracy, land reform, and social justice while guarding their organizational independence. Joseph Cyna, a Socialist leader, gave Karski copies of the Manifesto of the Wolność on May Day, 1940, to distribute on the train to Warsaw.
Poland maintained a unique stance among occupied European nations by completely refusing to form any legal collaborating body. Karski noted that unlike other occupied regions, Poland never produced any pseudo-legal body or provincial head collaborating with the Germans.
The Secret Press and Conspiratorial Apparatus
A vast network of secret newspapers, fed by clandestine foreign radio monitoring and hidden hand presses, maintained Polish morale and political awareness. Young operators listened to the BBC, WRUL, and WCBX in soundproof hideouts to transcribe news. The press utilized small formats and the three-system distribution method where couriers only knew the immediate contact behind and ahead of them. Józef Piłsudski famously printed the underground Robotnik using a Bostonka hand press in a Łódź cellar between 1899 and 1901.
Effective underground operations rely on prosaic methods and inconspicuousness rather than sensationalism. Karski maintained an apparatus featuring four organization offices, meeting places in commercial offices, archives in a restaurant, and his personal office in Mokotów. The underground utilized standardized administrative reporting procedures and coded systems to gather and verify political consensus. Karski circulated numbered reports among political leaders, and if they agreed, they initialed their copies and returned them to be filed as historic documents.
Maintaining security in the underground required keeping private living quarters strictly separated from political work. Karski's private address was kept secret from everyone except his closest family member and personal liaison girl to ensure a minimum level of security. Liaison women bore the most severe hardships, constant exposure, and brutal treatment in the underground network. A 22-year-old liaison worker was caught in a trolley car and subjected to brutal torture in prison, while a former high school teacher named Mrs. Pawlowska hanged herself in her cell with her own shirtwaist after being tortured.
3. Arrest, Torture, and Escape
Underground couriers operate under strict rules where the assigned guide holds total command and responsibility for the journey. Each courier is assigned a specific route and guide who knows all intermediary stops. The guide is physically attached to the courier, nicknamed patient, and must never leave his ward until delivery to the neutral country.
The arrest of a single courier and subsequent torture can compromise an entire underground border route.
Karski recounts his journey toward the frontier with a guide who maintained absolute authority over the route and stopping points. When a guide named Franek failed to return, it became evident that he had been caught by the Gestapo and had likely revealed the complete route and all stopping points under torture. Franek's arrest led directly to the compromised stations and the ultimate capture of Karski and his guide.
Gestapo Interrogations
Underground operatives traveling through enemy territory rely on meticulously crafted false biographies to survive initial questioning. Karski carried papers identifying him as the son of a teacher in Lwów, a detail chosen because the city was under Russian occupation and records could not be easily verified by the Gestapo. Inspector Pick utilized theatrical buffoonery and a swift cross-examination style, backed by guards delivering specialized strikes behind the ear with rubber truncheons designed to inflict maximum pain without causing unconsciousness. During his interrogation at Prešov, Karski maintained he was a student fleeing Soviet occupation to study in Switzerland.
A young SS lieutenant trained in an Ordensburg attempted to convince Karski to act as an intermediary for Polish-German collaboration under the banner of the Pax Germanica. The SS lieutenant brought Karski into a redecorated room, offered him brandy and cigarettes, and rhapsodized about the New Order before resorting to violence when refused. Facing inevitable death, severe physical damage from beatings, and the dread of betraying comrades while half-conscious, prisoners resorted to using hidden razor blades. After surviving multiple beatings and losing four teeth knocked out during the beatings, Karski smuggled a razor blade from the lavatory and slashed his wrists in his cell after spending three days spent in the cell without disturbance.
The Hospital Rescue
While recovering in a Slovakian hospital under Gestapo guard, Karski is shielded by sympathetic doctors, nurses, and local patients who bring him gifts, supply newspapers, and attempt to delay his discharge by exaggerating his illness. A nun in the Prešov hospital warns Karski to feign weakness so she can keep him hospitalized longer, and patients send him chocolates and oranges. Reaching the fifth day, the point when lying inertly in bed became intolerable and Karski asked for a newspaper, he read a Slovakian newspaper headline stating France Surrenders, followed by an article claiming England Commits Suicide by Continuing to Resist, which inspires him to pray for British resilience after remembering his visits to England in 1937 and 1938.
Under extreme torture and the threat of cracking, resistance members view suicide and cyanide as necessary defenses.
A nun visits Karski in the Polish hospital and slips a cyanide pill under his pillow, which he subsequently hides in his perineum using flesh-colored adhesive. The Polish underground facilitates escapes by bribing guards with money and forged papers, intending to later exploit them by holding the threat of Gestapo exposure over their heads. The young doctor in the Polish hospital informs Karski that the Nazi guard has been successfully bribed to look away at midnight. Following a young doctor's instructions, Karski strips off his hospital pajamas at midnight, walks down to the first floor, spots a rose on the window sill, and jumps into the arms of waiting men.
The escape plan relies on clear instructions:
- Wait for the doctor to pass the room and light a cigarette at midnight as a cue.
- Go to the first floor and locate the window sill marked with a rose.
- Jump from the sill into the arms of the men stationed below.
- Quickly dress in the clothes provided by the rescuers.
Rescuers transport the weakened escapee through woods, across muddy fields, and over a river using a small canoe while fighting a strong current. During the river crossing in an overloaded canoe, Karski falls overboard, but a burly rescuer named Staszek Rosa's associate calmly pulls him back by the collar while steering with one oar after about fifteen minutes of steady walking pace through the woods after the rescue and one hour spent fighting the river current in the canoe. Staszek Rosa informs Karski after the successful escape that they had two orders: to do everything to save him, or to shoot him if they failed during the crossing with five people squeezed into the small canoe.
4. Eyewitness to the Holocaust
Karski undertook perilous undercover missions into the Warsaw Ghetto and the Bełżec death camp to gather firsthand evidence of the systematic extermination of European Jews.
Inside the Warsaw Ghetto
You witness underground contacts guide Karski into the sealed Warsaw Ghetto through a secret underground cellar passage. He meets secretly in a ruined house with the head of the Zionist organization and the leader of the Jewish Socialist Alliance, the Bund. Their joint presence signifies that the information represents the entire Jewish population of Poland dying as a unit.
Karski meets the two Jewish leaders in a huge, empty, half-ruined house in the Warsaw suburbs, sitting in an old armchair with two bricks stacked under one leg while candles cast dim light. The Zionist leader weeps like a whipped child, asking why he should go on living when his entire people are being murdered.
The Jewish Underground demands that Allied governments bomb German cities with warnings of mass reprisals, execute German prisoners of war to force a change in Nazi practices, and negotiate financial ransoms or exchanges. Deportations begin in July, starting at five thousand victims daily and increasing to ten thousand daily. Engineer Czerniakow, chairman of the Jewish community, commits suicide when he receives the German demand for ten thousand people daily to report for work.
Karski observes streets filled with corpses stripped of clothing to avoid burial taxes, starving children playing, and a brutal hunting exhibition by Hitlerjugend boys. He watches through a slit in a window shade as a young blond Hitlerjugend boy casually shoots and kills a man in the street for target practice. Szmul Zygelbojm, representative of the Bund on the Polish National Council in London, relentlessly questions Karski for minute details of the ghetto before turning on the gas in his apartment and dying on May 12, 1943.
The Bełżec Death Camp
You see Karski plan to enter the Bełżec death camp using the identity papers and uniform of an Estonian guard serving under Gestapo supervision. Corruption, chaos, and bribery among the multi-national guards make such disguises viable since papers are rarely inspected at designated gates.
- Wear the uniform of a bribed camp attendant.
- Use papers bought from a guard who has left the service.
- Enter through gates guarded only by Germans or Ukrainians to avoid recognition by real countrymen.
- Mingle with the mob of mixed attendants when leaving the camp.
Karski leaves Warsaw with a Jewish underground member, travels to Lublin, takes a hay cart through dirt tracks to Bełżec, and obtains an Estonian uniform left at a secret grocery store run by an underground farmer. The Nazis use quicklime on the floors of freight cars to systematically burn victims and prevent the spread of disease. Quicklime combined with moist flesh generates high heat and dehydrates the body, causing victims to burn to death and consume their flesh before dying.
Karski watches as 120 to 130 Jews are crammed into each of the 46 freight cars whose floors are covered with thick, white quicklime powder, before the doors are sealed for a journey to an empty field. Father Edmund, chaplain of the Warsaw division, makes Karski bare his chest and hangs a scapular containing the Eucharist around his neck during a quiet dawn service before his 21-day journey from Warsaw to London.
