Lev's fear keeps him from doing what he feels he needs to do (help Kolya). This will be a challenge for Lev throughout the rest of the novel as he grapples with his fear on one side and his loyalty and sense of what’s right on the other. While Colonel Grechko was obviously an important person in the NKVD, we see here just how important he is for his letter to be able to command the attention of a group of soldiers. The soldiers’ disgust at the hanging “meat” strongly emphasizes the despair of the siege. These soldiers, being soldiers, have seen death. But even they are horrified by the things that the besieged people of Leningrad have been pushed to do.
