The weather was terrible , the roads were poor and the army had to help the tens of thousands of civilians who were retreating along with soldiers and who had almost no supplies or food . But the bad weather and poor roads worked for the Serbians as well , as the Germans and Bulgarians could not advance past the Albanian mountains , and so the thousands of Serbians who were fleeing their homeland managed to evade capture . However , hundreds of thousands perished due to hunger , disease , thirst , hypothermia , and because of attacks by enemy forces and Albanian tribal bands , carried out in revenge for the massacres committed by the Serb army against Albanian civilians in 1912-13 , during the Balkans Wars
