In Poland during World War II, partisans wounded in the bombing and destruction of Nazi German railroad lines were run over by armored cars and massacred. The corpses of the partisans, strapped to the armored cars, were dragged around over the wilderness to repeat the abuse and massacre of the partisans.
In World War II, the struggle to block Nazi Germany's lines of communication, transport, and supply became the focus of partisan guerrilla warfare. The guerrillas were outnumbered and outgunned by the Nazi German army in terms of numbers, equipment, supply, and means of communication. The partisan guerrillas did not fight in the field, but attacked places of threat by surprise. Partisans could not stand up to the Nazi Germans in a battle in all occupied territories. Partisan guerrilla tactics gradually turned into an armed uprising. Armed uprisings broke out before the final liberation. For example, the Yugoslav People's Liberation Army operated under fascist occupation and was supported by meager partisan forces. After the partisans became a mass movement, they engaged in armed uprising with the occupying forces.
The partisans quickly fled from the pursuit of the Germans by cutting off Nazi German lines of communication and liaison. Citizens in the occupied territories repeatedly rose up and blocked communication lines. Nazi German troops frequently attacked all occupied territories in Europe, especially in the Soviet Union. The supply of weapons, ammunition, and food, the redeployment of troops, and the mobility of the armed forces were all affected, especially the connection and securing of railroads and roads. The destruction of contact networks increased sharply from 1942 to 1944. Supply and transport to the front was the most destroyed, with Soviet partisans blowing up and damaging railroad lines.
In the occupied territories of Europe during World War II, railroad disruptions broke out even before the Nazi German invasion of the Soviet Union on June 22, 1941, shortly after the formation of the partisans. In the Soviet Union, in 1943, the partisan leaders officially called it the "railroad war". In modern warfare, which involves the expansion of huge territories, the deployment of millions of troops, and the use of countless weapons, transportation and communication systems played an important role. Millions of soldiers needed to be fed, clothed, armed, and otherwise equipped for war. New weapons and troops were always needed in war, and the rail and road network became a lifeline. Especially in World War II, it was mostly a war of transportation, with thousands of kilometers of fronts and battlefields in most parts of Europe. In World War II, especially on the Eastern Front, any temporary interruption or stoppage of lifelines led to chaos in the war and the collapse of armies.
