Seekrieg 5 – Newcastle Raid

March 25, 2017

This weekend the local HMGS-South group played a WWI naval game using the Seekrieg 5 rules. A German squadron has bombarded Newcastle and is returning home but is spotted by a British dirigible. While still 200 miles from Heligoland, it is intercepted by a British squadron to the SSW.

German Squadron:
Armored cruisers Roon, Yorck, Prinz Adalbert
Light cruiser Pillau

British Squadron:
Armored cruisers Defence, Shannon
Light cruisers Arethusa, Aurora

We quit after 11 turns due to the time. On the British side, Defence and Shannon were lightly damaged with no critical hits, Arethusa was gone and Aurora was down to 16 knots with boiler and engine damage. On the German side, Roon had more than 40% damage and had lost a main turret, Yorck was gone, Prinz Adalbert had light damage and Pillau had medium damage.

 

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.

Seekrieg 5 – North Sea Encounter

November 26, 2016

This weekend the local HMGS-South group played a WWI naval game using the Seekrieg 5 rules. Initially the game was set up with a four ship division on each side, but we scaled it down to two ships on each side due to the low holiday weekend turnout.

The forces started 20,000 yards apart in good visibility. The British had two Iron Duke class battleships and the Germans had the Baden and a Konig class. The players rolled for crew quality and all ended up the same. The game ended when the lead British ship was destroyed by a magazine explosion.

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.

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.

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.

Seekrieg 5 – Falklands 1914

July 9, 2016

This weekend the local HMGS-South group played a WWI naval game using the Seekrieg 5 rules. The scenario was based loosely on the situation in the Falklands in December 1914, but with significant historical revisions to produce a more balanced battle.

The scenario deviates from history just before von Spee’s squadron reaches the Falklands. Von Spee is alerted to the presence of a strong British force, hides until dawn on 9 December and then uses the cover of fog to start for the Argentine coast. The British divide their forces to search, and one element finds the Germans. The scenario was scaled to give one ship to each of the five players.

Visibility 12,000 yards.

British: battlecruiser Invincible, light cruiser Bristol

German: armored cruisers Scharnhorst and Gneisenau, light cruiser Dresden.

The German ships (especially Scharnhorst) were given an advantage in crew quality to help the scenario balance.

After about 4.5 hours of play, we stopped play. Damage was about even, mostly to Scharnhorst and Invincible. No ship had been sunk or crippled.

 

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.

WWI Naval – Gulf of Finland

February 13, 2016

This weekend the local HMGS-South group played a WWI naval battle. In this hypothetical engagement, the Germans send a portion of the High Seas Fleet into the Gulf of Finland in an attempt to engage and destroy the Russian Baltic Fleet. The date is March 15, 1915. The scenario is similar to a previous test.

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

Rules: Computer code (described here).

Visibility 16,000 yards. Wind southerly at 8 knots. Seastate 2.

Status at the end of the game: Fin2-end-status

Damage output file: SK-Normal-Fin2-2016-1-23 excerpt.txt

We quit at this point due to time. The damage was relatively even. The Russian destroyers and torpedo boats and the German light cruisers did most of the fighting. One dreadnought had been sunk on each side.

Wings of War AAR

August 9, 2015

This weekend the local HMGS-South group played a Wings of War (aka Wings of Glory WWI) game. Two Bristol F.2B on a bombing mission are escorted by two Camels. The Germans intercept with two DVII and two DVa.

The score at the end was one fighter lost on each side and the target bombed by one Bristol. The second Bristol was unable to overfly the target due to rudder damage.
