This book was the only one written by Boleslaw (as he was known) and covers the time when he served in a Polish cavalry unit, fighting for the Russians during WWI.  Based on his experiences covers a short time from the beginning of the Russian Revolution when the Russian army began to break up through the forces of defeat, starvation, useless slaughter and Communist propaganda.  His unit (there were similar units fighting for the Germans and Austrians), then decided that their oath to the Czar was null and void and they attempted to reach fellow Polish units across the front lines. 

A look at racial and ethnic quotas from around the world show that they are either counter productive, used to lower standards, destroy meritocracy or lead to corruption. What positives have we seen after decades of quotas here in the United States? Will quotas ever end and with the changing demographics of the nation, how can they be justified when the minority becomes the majority? This is a thoughtful article which provides examples of failed quotas from around the world.https://quillette.com/2020/07/03/affirmative-action-in-a-multiethnic-nation/
