This scenario is based on the Battle of the Yellow Sea during the Russo-Japanese War. The initial positions are based on the following references:
“The Russo-Japanese War 1904-1905 British Naval Attache Reports,” Plate 7.
H. W. Wilson, “Battleships in Action,” Chapter XII.
Julian S. Corbett, “Maritime Operations in the Russo-Japanese War, 1904-1905, Vol 1, Chapter XXII.
Bill M., “The Battle of the Yellow Sea,” The Naval Wargames Society, http://www.navalwargamessociety.org/scenarios.html
The battle might be called ‘Encounter at Encounter Rock’ since several references mention that location. None that I have seen state where the rock is (or was), but an approximate location can be inferred from the first reference above: 24 NM SE of Port Arthur.





Three additional Japanese destroyer divisions are strung out to the south and southeast of the Russians. Three Japanese torpedo boat divisions have been omitted from the scenario.
The sea conditions and orders of battle are listed on Page 1 of the Narrative file:
Player reports (not needed since there were no human players):
Plot from 1230 to 1440hrs
This plot shows the entire battle, with the Russian movements in red and the Japanese in blue.
Plot from 1230 to 1330hrs
Initial movements and deployments of the units during the first hour. The AI ordered the Japanese divisions to form up, but this required the 3rd Division to pass close to the Russian squadron. As a result, the division’s small protected cruisers took significant damage from the rear Russian ships before joining the rest of the Japanese fleet.
Both sides eventually formed battle lines heading east. Once on roughly parallel courses (with low range rates) and in effective range, the serious shooting began.
Plot from 1330 to 1417hrs
Unit movements continued. The Japanese destroyers took station on the disengaged side of the battle line until the Russian line was significantly weakened. At that point (1400hrs) a general torpedo attack was ordered and the destroyer divisions headed south.
Plot from 1330 to 1417hrs
The battle lines fight in detail. Torpedo salvos aimed to cross the paths of Russian battleships missed because the targets sank.
Plot from 1330 to 1417hrs

End of game status:
Battleship primary battery gunnery logs
These are less useful than those of dreadnought battles since much of the damage was caused by secondary batteries.
