However, by 1943 it became apparent that the allied invasion of Europe would not come in time, and that in all probability the Red Army would reach the pre-war borders of Poland before the invasion had well begun. In February, 1943, general Stefan Rowecki amended the plan. The Uprising was to be started in three phases, the first being in the East (with main centres of resistance in Lwów and Wilno), before the advancing Red Army. The second part was to include armed struggle in the belt between the Curzon Line and the Vistula river, while the third part was to be a nationwide uprising in all of Poland.
