At the beginning of November 1944 the XXI Mountain Corps retreated from Albania to Podgorica in Montenegro. In mid-November they tried to break through Danilovgrad and Nikšić toward Sarajevo, but Yugoslav partisan forces supported by two British artillery batteries, code-named Floydforce, stopped them after ten days fighting. At the end of November 1944 they had to retreat through a much longer route, via Kolašin, Prijepolje, and Višegrad.
