I used to take it as a given that all Socialist Realism was crap. It could be amusing, but the need to toe the party line and to portray heroes of socialism was fundmentally incompatible with good literature. After reading this surprisingly good book, I'm no longer so sure of my negative judgment.
The Iron Flood is a Soviet Anabisis with Kojukh in the role of Xenophon. Like Xenophon's famous often imitated story, it is about an army trapped in a hostile land that must fight its way against all odds back to its homeland, only to find when it finally arrives that more fighting and lack of appreciation for its great deeds are the only reward. Like Xenophon, Kojukh is a doubtful leader, thrust to the fore almost against his will, not always respected, but always situationally aware and smarter than anyone else in the room. And curiously, this story takes place only a few hundred miles away from the location of the Anabisis.
But the best thing about this book is its narrative point of view. The action is presented through a narrow field of view. As you read, you see only a fraction of what is going on around you, and you have to piece together a bigger picture. It's the same perspective that a common soldier or one of the refugees in the midst of the action would have had. Sometimes it is confusing, but it works because there is always enough information that the bigger picture gradually becomes clear. And there are very few individuated characters here. Most of them have no names. They effectively merge together into a collective, so that people themselves become the main character. Others have tried this. I remember something similar in Pushkin's Boris Godunov, but it isn't easy to do, and I felt that Serafimavich pulled it off quite effectively, even as he carefully delivers standard party approved politics by castigating both left and right deviationists as he walks the tightrope of proper Stalinism. I don't know if this could ever have given birth to a mainstream genre of books of Socialist Realism. I don't think that Furmanov or Gladkov or Ostrovsky could have written in this style. It is a style that feels experimental and exciting, almost worthy of the kinds of things that the Futurists and Absurdists were doing in Russia at around the same time before Stalin shut them down and packed them off to Siberia or drove them to suicide.
