DESCRIPTION

In the spring of 1941, the German Blitzkrieg crushed the Balkans, rapidly overrunning Yugoslavia and Greece. The battered remnants of the defeated Allied armies evacuated to the island of Crete and prepared to defend it. Faced with the threat of air attacks from the Allied air bases on Crete and pressed for time, men and equipment on the eve of Operation Barbarossa (the invasion of the Soviet Union planned for June), Adolf Hitler decided to launch a lightning air assault to take Crete: Operation Mercury!

On May 21, 1941, German paratroopers, brave tough, battle-hardened and with esprit-de-corps second to none, formed the spearhead of Hitler's daring airborne assault. Hastily assembled, these elite troopers jumped into an unexpected maelstrom of fire and lead that decimated their ranks.

For the next eight days, the depleted airborne forces, bolstered by a reinforcing Mountain Division, were locked in a gripping life-and-death struggle against fierce resistance from the defending British, Greek, Australian and New Zealander troops.

When it was over, though Germany prevailed, over 7,000 German soldiers, including one in four paratroopers, lay dead on the battlefield. Operation mercury was a German victory, but a Pyrrhic one at best. Adolf Hitler was so shocked by the heavy German losses on Crete that he never deployed his elite paratroop units again in a major airborne operation.

Operation Mercury allows you to recreate this bitter struggle for Crete at company/battalion level. The game system, based on Gene Billingsley's award-winning GMT Operational System which first appeared in Silver Bayonet, Operation Shoestring and Air Bridge to Victory, allows for multiple combat options. The system also takes into account unit morale and efficiency as well as formation strength when resolving combat.

VASSAL MODULE (v1.0)

A very first VASSAL module for this old hidden gem by Gene Billingsley & Vance Von Borries.

You can download the Rulesbooklet (updated October 2019) including the errata of August 14th, 1995 as well as many clarifications from my discussions with Vance and Tony.

You can also download the Module User Guide to familiarize yourself with the module and its specificities. This User Guide is also accessible via the Help menu of the module.

There are a lot of automated features to make the game more fluid and enjoyable to play. Thus, a number of interactive features are directly executed from the right click menu of pieces, the DRMs being taken into account, and the effects take place automatically, such as:

etc...
 * Rolls for efficiency checks
 * Paradrop and Amphibious Drifts
 * Air readiness
 * Naval Reffiting
 * Victory Points Track
 * Map buttons displaying Ports
 * Supply Status Adjustment
 * Game Turns
 * Air Interdiction Level effects
 * Control Markers

Allied naval units are accessible only to the allied player and a blind game system was designed to be faithful to the game. A system for "revealing" units is provided when needed, so the originality of the system "Detection and Naval Search" is preserved. In the same way, the allied player does not really know where the German Luftwaffe gonna strike.

Useful new Markers and new Player Aid Cards have been added and many other features to make the game more pleasant.

If you notice errors, omissions, misprintings, bugs, wrong setups or anything else please fell free to contact me by email and report it to me. I will make the corrections accordingly. Thank you.
