While Scandinavia's 'Viking Age' is one of the most studied aspects of early medieval history, much less has been published about the centuries which followed. Yet the armies of Sweden, Norway and Denmark offer fascinating differences from the rest of medieval Western Europe, both in their organisation and their war gear. This second of two books covers the period which saw both expansion in the Baltic, and long wars born of the attempt to bring Scandinavia under a single monarchy - the Union of Kalmar. In the North, as elsewhere, the perfection of plate armour could not prevent the steady decline in the importance of the 15th century mounted knight in favour of the well armed infantryman.
