Seekrieg 5 – Tsushima

This weekend the local HMGS-South group played a Russo-Japanese War naval game using the Seekrieg 5 rules. The scenario included battleships from the Battle of Tsushima.

The battle was fought in calm seas and hazy weather, visibility 12,000 yards. The lead ships started about 12,000 yards apart.

Japanese ships in a single line ahead:
Mikasa, Asahi, Fuji, Shikishima, Chin Yen

Russian ships in two divisions, each in line ahead:
Kniaz Suvarov, Imperator Alexander III, Borodino, Orel
Oslyabya, Sissoi Veliki, Navarin, Imperator Nicolai I

Crew quality was randomized, with the Japanese having a probable advantage:

Japanese:
1-20%       +1
21-80%    +2
81-100%  +3

Russian:
1-30%        -1
31-90%       0
91-100%   +1

The battle opened with the Borodino class ships firing at the four new Japanese battleships, the Oslyabya firing at the Chin Yen and the four Japanese battleships firing on the lead pair of each Russian division. The guns of the remaining ships would be out of range for several turns. The Japanese soon switched to firing their primary guns on the four Borodino class and their secondary guns on the older Russian ships. The Imperator Alexander III lost an engine room on the first turn, forcing her to leave the formation. That was the story for the rest of the battle, with the Russian first division taking most of the damage.

After 14 turns and more than four hours of real time, the damage was:

Russian:
Kniaz Suvarov                      3 tiers, speed reduced to 7 knots
Imperator Alexander III    1 tier, speed reduced to 9 knots
Borodino                               light damage
Orel                                        8 tiers, speed reduced to 11 knots,
–                                               no main battery, sinking
Oslyabya                               light damage
Sissoi Veliki                          light damage
Navarin                                  light damage
Imperator Nicolai I             light damage

Japanese:
Mikasa                                    light damage
Asahi                                       light damage
Fuji                                           light damage
Shikishima                             1 tier, speed reduced to 8 knots
Chin Yen                                 1 tier

 

 

Risikoflotte Risked – 1914 Naval AAR

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).

Player briefings: Copenhagen 1914

Visibility 14,000 yards, improving gradually. Wind westerly at 8 knots. Sea state 3.

Status at the end of the game: Cope IO

Damage output file: Cope Short output

Computer code (described here)

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.
