smaller groups in 1942. There was also the People's Army (Polish Armia Ludowa or AL), backed by the Soviet Union and controlled by the Polish Workers' Party (Polish Polska Partia Robotnicza or PPR), though significantly less numerous than the Home Army. In February 1942, when AK was formed, it numbered about 100,000 members. In the beginning of 1943, it had reached a strength of about 200,000. In the summer of 1944 when Operation Tempest begun AK reached its highest membership numbers. Estimates of AK membership in the first half of 1944 and summer that year vary, with about 400,000 being common. With the imminent arrival of the Soviet army, the AK launched an uprising in Warsaw against the German army on 1 August 1944. The uprising, receiving little assistance from the nearby Soviet forces, eventually failed, significantly reducing the Home Army's power and position. About 200,000 Poles, most of them civilians, lost their lives in the Uprising. Effect on the Polish population The Polish civilian population suffered under German occupation in many ways. Large numbers were expelled from land intended for German colonisation, and forced to resettle in the General-Government area. Hundreds of thousands of Poles were deported to Germany for forced labour in industry and agriculture, where many thousands died. Poles were also conscripted for labour in Poland, and were held in labour camps all over the country, again with a high death rate. There was a general shortage of food, fuel for heating and medical supplies, and there was a high death rate among the Polish population as a result. Finally, thousands of Poles were killed as reprisals for resistance attacks on German forces or for other reasons. In all, about three million Poles died as a result of the German occupation, more than 10% of the pre-war population. When this is added to the three million Polish Jews who were killed as a matter of policy by the Germans, Poland lost about 22% of its population, the highest proportion of any European country in World War II. Poland had a large Jewish population, and according to Davies, more Jews were both killed and rescued in Poland, than in any other nation, the rescue figure usually being put at between 100,000 and 150,000. Thousands of Poles have been honoured as Righteous Among the Nations – constituting the largest national contingent. When AK Home Army Intelligence discovered the true
