The Czech National Council (ČNR), lacking significant supplies to support the uprising, fearing large-scale destruction of Prague, and in the wake of the overall German surrender, came to an agreement with the Germans in which the German troops were to leave Prague under conditions of ceasefire. Some SS units, however, continued their attacks against the Czech insurgents in Prague. The 1st KONR Division, its relations with the ČNR broken down and realizing no quarter could be expected from Soviet forces, joined the SS and other German troops in a wary alliance of convenience and started moving west. The KONR 2nd Division had already contacted the Americans and started the march west.
