History for the day

War History Online has an article by Colin Fraser about the Warsaw Uprising:

Throughout World War Two, the people of Poland were trapped between Nazi Germany and their old enemy, the Russians. Occupied by Nazi Germany since 1939, the prospects for their freedom looked very bleak indeed come 1944. Poland was faced with either Nazi rule or domination by the Russians.
Russia’s army was now rapidly approaching from the East and, after the Katyn massacre (when Russia executed thousands of Polish officers), fighting between Polish partisans under the Polish Home Army and the Soviet partisans in Poland, and Stalin’s hunger to draw more countries into the Soviet Block, many Poles were worried one conqueror would simply be replaced by another.
With this bleak prospect looming on the horizon of a still bleak situation, Commander Tadeusz Bór-Komorowski of the Polish Home Army devised Operation Tempest: a huge, coordinated effort by the underground resistance to rise up across Poland, focused on Warsaw, to kick the Nazis out before the Russians swept into the major cities on the west side of the Vistula river. It became the largest military operation by any resistance movement in an occupied country in World War Two.
Though wary and distrustful of the Russians, the Home Army timed their uprising with the approach of the Red Army through Eastern Poland, with the hopes that they would offer some assistance or, at least, divert the Germans away from Warsaw. In fact, almost the opposite was true.
First-hand accounts from people living in Warsaw at the time claim that Russian planes that were heard constantly flying missions against the Germans in the weeks before, Operation Tempest suddenly stopped all activity when it began. Stalin had ordered his troops to halt their advance towards Germany. He even issued direct orders that all support for the Home Army’s efforts should be cut off and any Home Army units in Russian-controlled areas should be apprehended and disarmed.
Nevertheless, four days after Operation Tempest began on 1 August 1944, the Home Army controlled large areas in Warsaw, and the fight was on for the liberation of the city.
Many of the Polish resistance forces had been training in urban combat for years in preparation, but weren’t ready for a prolonged struggled against the professional German army and vicious SS troops.
The German’s reaction to the uprising was swift and brutal. Hitler ordered Heinrich Himmler of the Waffen SS to direct mass, indiscriminate executions of citizens.
On 5 August 1944, in just the western suburb of Wola alone, SS troops murdered tens of thousands of civilians of all ages and sexes, with estimates ranging from twenty thousand to a hundred thousand killed. By the end of the uprising, as many as two hundred thousand citizens were killed in and around Warsaw.
The Nazis quickly noticed, however, that the mass killings only seemed to strengthen the resolve of the Polish resistance fighters and changed their strategy to focus on the military operation to take back the city, street by street, house by house. The Home Army had between twenty thousand and fifty thousand active fighters. The Germans began with some twenty-five thousand troops, which was soon increased with more reinforcements and tanks to retake the city.
The battle quickly became a bloody stalemate, with the Germans using everything from continuous, widespread bombings, to tanks with human shields. The Poles had set up many barricades and ditches, however, making any progress by German armor very slow.
Through the month of August, the Germans made slow, steady progress retaking the city. Section by section, the resistance fell. By early September, Bór-Komorowski agreed to talks with the Germans, which made progress for several days and achieved things like the evacuation of twenty thousand civilians.
The talks were broken off by 11 September 1944, however, as the Red Army, once again pushing forward against the Germans, was moving through the city of Praga, just east across the Vistula from the center of Warsaw. By 13 September 1944, the Germans had retreated across the Vistula and destroyed the bridges.
This brought a great deal of renewed hope to the Home Army and the Poles of Warsaw. Unfortunately, all help they finally did receive was either too little, too late, or both. Not wanting to anger Stalin, it took Britain and America a woefully long time to airdrop supplies to Warsaw. These drops, containing food, weapons, ammunition, medical supplies, etc., were too few, and often landed in German-controlled areas.
Perhaps the biggest boost to Home Army moral came when General Zygmunt Berling of the Soviet’s Polish First Army committed troops to send over the Vistula to reinforce his countrymen. Had this move come several weeks earlier, it might have been a huge help. However, after weeks of fighting, the Germans had regained control of all but a small sliver of the Vistula’s west bank. Even with some artillery and air support from the Russian Army, Berling’s units attempting to cross the Vistula met with very little success. About nine hundred men managed to get across and help their comrades. This was outweighed by very heavy losses of nearly six thousand casualties.
After many pleas to the Soviets for an intervention with no answer or substantial help, the Home Army ended their struggle on 2 October 1944. They disarmed, and the Germans once again controlled the city. The entire remaining population of Warsaw, as many as a half million people, were taken out of the city and moved to POW, concentration, and labor camps, or relocated to other areas in Poland and the Ukraine.
The Germans then proceeded to level much of the city. Between destruction from the war, earlier uprisings in Warsaw, and now the reaction to Operation Tempest, nearly ninety percent of Warsaw was destroyed. The Germans put particular focus on destroying monuments, museums, academic institutions, libraries, and archives. After the Russian’s “liberated” Warsaw and the rest of Poland, and instituted Soviet rule, talk of the Warsaw Uprising was actively suppressed. Many leaders of the Home Army and other Polish resistance were smeared as Nazi collaborators, put through mock trials, and sent to the Gulag. It would be many decades before the brave freedom fighters of Warsaw were to be commemorated by a small monument to their memory and heroism. Only today is the bravery of the Home Army being recognized in their native land.
Much of the documentation of the Warsaw Uprising managed to survive the destruction of the city. The Wikipedia page for the event has a stunning photo gallery of life in Warsaw before and during the fighting, Polish resistance fighters, and the vast destruction of the city. American Radio Works did a segment on the Uprising, as well, with first-hand accounts from survivors.

Rico says that Mila 18 by Leon Uris was a great book about a bad time in Warsaw... (Of course, it only took another seventy years for that whole Communist thing to go away.)
