Throughout the wars undertaken by Frederick the Great, probably his greatest resource was his infantry.

It is a mark of the king''s determination that despite wars which almost destroyed both Prussia and its army (such as the Seven Years'' War), he was able to maintain its numbers – even if the quality declined as the attritional campaigns took their toll.

Philip Haythornthwaite examines the uniforms, tactics and organisation of Frederick''s infantry in detail – a fighting force that contested battles such as Mollwitz, Hohenfriedberg, Kesselsdorf, Liegnitz, Burkersdorf and the siege of Prague.
