Rehabilitated in 1990; a national hero

In September 1940 a Polish officer let himself be caught in a German street round-up in Warsaw, so that he would be sent to Auschwitz. Inside, Witold Pilecki built a resistance network and smuggled out some of the first reports of what was happening in the camp. Eight years later he was executed, not by the Germans, but by Poland's new communist rulers.

A soldier of the borderlands

Born in 1901, Pilecki fought as a young volunteer1 in the Polish-Soviet War of 1920 and became a reserve cavalry officer and landowner. He fought in the September campaign of 1939, then helped found one of the first underground organisations in occupied Warsaw, the Secret Polish Army2.

Into Auschwitz

The underground knew little about the new camp at Auschwitz. Pilecki volunteered to find out. On 19 September 1940, using the false name Tomasz Serafiński2, he allowed himself to be seized in a round-up and was deported to the camp, where he received prisoner number 48592.

The resistance inside

In the camp Pilecki organised a secret network of prisoners3 that shared food, helped the weakest and gathered intelligence. Its reports, smuggled out through released prisoners and escapees4, reached the Polish underground and, through it, the government in exile in London. On the night of 26 to 27 April 1943 he escaped2 with two companions and wrote a detailed report on the camp, known as Witold's Report.

The Warsaw Uprising and after

Pilecki fought in the Warsaw Uprising of 1944 and was taken prisoner5 by the Germans. After the war he joined the Polish II Corps in Italy and then returned to communist-ruled Poland to gather intelligence, on the orders of General Anders, for the Polish authorities in the West. Arrested in 1947, he was tortured, condemned in a show trial and shot in Warsaw's Mokotów prison on 25 May 19485. His body has never been identified.

Remembered at last

For decades the communist authorities erased his name. Pilecki was rehabilitated in 19902, and today he is honoured in Poland as a national hero and widely regarded as one of the bravest figures of the Second World War.
