what happens to Albert and Paul after they evacuate the village? how does paul help Albert?

At night, Kropp and Paul are brought to the "chopping-block"; Paul is afraid the knife-happy surgeons will amputate them. When the surgeon examines his leg wound, Paul squirms, and the surgeon orders chloroform to sedate him. Wary he will be operated on while under, Paul promises to keep still. The surgeon removes a piece of shell and says Paul can leave tomorrow. Paul later bribes the army medical sergeant-major to keep him and Kropp together. Both Paus and Kropp help each other by simply being there, they are more like family than their actual families.
