Tsushima – Russo-Japanese War Naval AAR

May 13, 2017

This weekend the local HMGS-South group played a Russo-Japanese War naval battle based on the Battle of Tsushima. In order to make the game more balanced, the Russian ships were not handicapped to reflect their historical performance.

Visibility 14,000 yards. Wind SW at 14 knots. Seastate 3

Status at the end of the game: tsus2 io

Damage output file: tsus2 out

Plot of ship movements:
0 to 30 minutes tsus2 plot 0-30
30 to 60 minutes tsus2 plot 30-60
60 to 90 minutes tsus2 plot 60-90

Computer code (described here)

We called the game after about 4.5 hours of play (90 minutes of game time). The damage was fairly even at that point. The Russian battleships were low on main gun ammunition and several were completely out, so their ability to continue the fight was limited.

Bay of Algiers, 1914, Again

April 15, 2017

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.

WW1 Naval – Churchill’s Idea

January 28, 2017

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

Coronel and the Falklands

October 19, 2016

The book “Fatal Choices, Wargames, Decisions and Destiny in the 1914 Battles of Coronel and Falklands” by Seth Owen includes historical and non-historical wargame scenarios associated with the cruise of the German East Asia Squadron. Several of these were played as solo exercises using this computer code. The code is not intended for small scale actions. The main drawback in using it is that orders can only be changed every 5 minutes. Using the options for automatic target selection and opening fire mitigates this to some extent.

The Battle of Cocos

The fight between the Sydney and the Emden. The damage the Sydney sustained seems to be more than in the actual battle.

The Battle of Samoa

A hypothetical battle between an Australian squadron including the battlecruiser Australia and von Spee’s squadron. The Australia takes significant damage. The Gneisenau runs out of 21 cm shells (her primary battery), in part because while the Australia was firing at Scharnhorst, Gneisenau could keep up a higher rate of fire. According to the NAVWEAPS site, the Scharnhorst class had 87.5 rounds per 21 cm gun.

The Battle of Coronel

The historical battle between Cradock’s squadron and von Spee’s squadron. The Scharnhorst runs out of 21 cm shells and the Gneisenau nearly runs out. This may be because the range was generally longer than in the actual battle, or because the penalties on rate of fire for poor visibility are not severe enough.

The Battle with Canopus

The fight between the pre-dreadnought battleship Canopus and the armored cruisers Scharnhorst and Gneisenau. Both armored cruisers ran out of 21 cm shells and the Canopus was finished off with the 15 cm secondary batteries. Torpedoes may have been a better choice. If this encounter had occurred historically, low ammunition after the Coronel battle would probably have caused von Spee to avoid Canopus.

Plot of ship movements: canopus-plot

The Battle of Coronel including HMS Defence

A battle between Cradock’s squadron, reinforced by the armored cruiser Defence, and von Spee’s squadron. This is a lot closer fight than the actual battle. With Scharnhorst sunk and Gneisenau out of 21 cm shells, von Spee’s squadron would probably break up into individual raiders.

The Battle of the Falklands

The historical battle between Sturdee’s battlecruisers and von Spee’s armored cruisers. The battlecruisers took more damage than in the actual battle, possibly because von Spee’s armored cruisers did not try to run.

Damage output file: falklands-output

Plot of ship movements: falklands-plot

The Battle of Stanley

A hypothetical battle between Sturdee’s  squadron and von Spee’s squadron, assuming that von Spee attacks before Sturdee is underway. The scenario in the book started with the Gneisenau and the Nurnberg approaching Stanley and the rest of von Spee’s squadron 15 nautical miles away. To give von Spee more of a chance, this exercise assumes that he approached with his squadron together. Timings for Sturdee’s ships getting underway are from Corbett, not from Owen’s book.

Jutland 100th Anniversary – Windy Corner

May 31, 2016

For the 100th anniversary of the battle of Jutland, the positions of the fleets at about 6 pm were set up, and various options for the deployment of the Grand Fleet were discussed.

No formal game was attempted since it would have taken more time than was available, but the capital ships were run through the deployment with automated targeting while we talked. The light forces were mostly ignored, but several torpedo attacks occurred anyway due to the initial courses. Since the German fleet did not turn away, the damage was much greater than historically. The poor visibility, particularly toward the north and east, allowed several devastating torpedo attacks.

Scale: 1/6000 miniatures, 500 yards/in ground scale.

Computer code (described here).
