When talking about the Spanish intervention in the Second World War, the first thing that comes to mind is the Blue Division. However, although it is true that this was the main Spanish involvement in the conflict, there are other much less known aspects of their intervention. One of these is the Spanish participation on the German side in the last months of the war which has been surrounded in rumors, myths and legends. After many years of research, this book tells the story of the reality of the struggle of those few Spaniards who refused to abandon their German comrades in their desperate fight to hold Berlin in the last days of the war. The author gives a day-by-day account of the last weeks of the war to defend Berlin, including information about anti-partisan operations of the Spanish in the north of Italy, the combat together with the Walloons of Leon Degrelle, and their participation in operations against the maquis in France while posted to the German secret service.
