Prelude to Disaster is one part of the Winterstorm Series, original designed by John Schettler and has the same Basic Rules like Edelweiss and Last Victory. The game covers the time between the end of the Soviet Winter counteroffensive and the beginning of the German Stalingrad campaign. In early May 1942, four Soviet armies stands poised to liberate Kharkov and seize the Dnepr River crossings, destroying all the German armies in the south Ukraine. The Germans themselves are preparing to nip the Soviet thrust at its base. Victory hangs in the balance and the entire course of the summers campaign will depend upon who can strike first. The game provides two scenarios that can be played to conclusion in a single sitting. The number of units on each side is large but not overwhelming. And play balance is such that either side has a chance to win. The game contains 720 Die- cut counters, one 34' x 22' game map, Army Organization Display, 2 rulebooks with historical commentary. - BoardGameGeek
