This weekend the local HMGS-South group played a fictitious naval battle set in the North Sea in May 1914. The British attempt to destroy the German fleet in the North Sea bases. The German fleet sails to fight in the Heligoland Bight. The scenario is based on the British strategy of destroying fleets which may become a threat (Copenhagen) (also), and the German concept of the Risikoflotte (risk fleet).

After more than four hours of play and 60 minutes of game time we called it a day. 5 British dreadnoughts were sunk and 2 were in a sinking condition. 2 German dreadnoughts were sunk and 1 was heavily damaged. The Germans could claim a tactical victory at this point but not a strategic victory.

This battle was played some years ago with an earlier version of the code.

This weekend the local HMGS-South group played a fictitious naval battle set in the Adriatic in WW1. On June 15, 1915, a few weeks after the Italian declaration of war on Austria-Hungary, the Austro-Hungarian fleet sails to attack Brindisi and to lure out the Italian fleet. The Italians are alerted and hope to avenge Lissa.

Visibility 14,000 yards. Wind WSW at 10 knots. Seastate 2.

After four hours of play we ended the game with the Austro-Hungarians having lost 2 battleships and all their destroyers and the Italians having lost most of their destroyers. Several cruisers on both sides were badly shot up.

This weekend the local HMGS-South group played a WWI naval game using a modified version of a scenario tested previously.

This fleet action is based on the Triple Alliance naval convention of 1913, as described in “The Great War at Sea” by Sondhaus. The plan was for the Italian and Austro-Hungarian fleets and any German ships in the Mediterranean to engage the French Fleet and block the Algerian troop transports. This scenario assumes that the war starts in February 1914, and that the British Mediterranean squadron joins the French.

The confrontation occurs north of the Bay of Algiers.

Visibility 18,000 yards. Wind NNW at 3 knots. Seastate 1

The French had more undamaged ships when we quit, so the troop transports should be safe.

This weekend the local HMGS-South group played a World War One naval game based on this March 9th 1915 memo (item 121 Jellicoe Papers) from the 1st Lord of the Admiralty. The idea was to send a fast division into the Baltic Sea and, in cooperation with the Russian fleet, blockade German ports. The Germans send the ships that were in the Baltic for training exercises.

The confrontation occurs off Aarhus, Denmark: aarhus-10nm-grid
