Ulica Miła 18 (or 18 Pleasant Street in English) was the headquarters "bunker" (actually a hidden shelter) of the Jewish Combat Organization (ŻOB), a Jewish resistance group in the Warsaw Ghetto in Poland during World War II. The bunker at Miła 18 was constructed by a group of underworld smugglers in 1943. The ŻOB fighters arrived there after their own hideout, at 29 Miła Street, had been discovered. The smugglers who had built it were helping the ŻOB as guides. From the Stroop Report 7 May 1943: The location of the dug-out used by the so-called select "Party Directorate" is now known. It is to be forced open tomorrow. The Jews testify that they emerge at night to get fresh air, since it is unbearable to stay permanently within the dug-outs owing to the long duration of the operation. On the average the raiding parties shoot 30 to 50 Jews each night. From these statements it was to be inferred that a considerable number of Jews are still underground in the Ghetto. Today we blew up a concrete building which we had not been able to destroy by fire. In this operation we learned that the blowing up of a building is a very lengthy process and takes an enormous amount of explosives. The best and only method for destroying the Jews therefore still remains the setting of fires. From the Stroop Report 8 May 1943: We continued today the operation against the dug-out of the so-called select 'Party Directorate' which we had discovered yesterday, as reported in my teletype message yesterday. We succeeded in forcing open the dug-out of the Party Directorate and in catching about 60 heavily armed bandits. We succeeded in catching and liquidating Deputy Leader of the Jewish Military Organization 'ZWZ' and his so-called Chief of Staff. There were about 200 Jews in this dug-out, of whom 60 were caught and 140 were destroyed, partly owing to the strong effect of smoke-candles, and partly owing to heavy explosive charges which were laid in several places. The Jews whom we caught had already reported that innumerable Jews had been killed by the effect of the smoke-candles.
