WW1 Naval – Dogger Bank

1st and 2nd Battle Cruiser Squadrons with the German line in the distance.

This scenario, based on the Battle of Dogger Bank (January 23, 1915), was an attempt to test the AI code against a human player. Information used by the human player was limited as much as possible to what would be available in an actual game.

The sea conditions and orders of battle are listed on Page 1 of the Narrative file:


Force reports:


Plot from 0710 to 1610 Hours

The single lines (red for British, blue for German) show the movement of the forces prior to contact. When contact was made, the individual ships were set out into their cruising formations. The British Battle Cruiser Force was in two squadrons in line ahead with a line abreast screen of one light cruiser squadron. The Harwich force was in three flotillas, each lead by a light cruiser. The German battle cruisers were in a single line ahead, with a circular cruiser screen ahead and two flotillas flanking the battle cruiser line.

Plot from 1616 to 1815 Hours

The Battle Cruiser Force was headed north-east at the time that the Harwich Force sighted smoke to the south-east. The BCF then reversed course to the south-east. The cruiser screen would take some time to regain station since the cruiser’s design speeds were only 25 knots.

Sighting of a German light cruiser heading west by the destroyers of the Harwich force occurred at 16:45. The human player assumed that heavier ships would be following this screening cruiser. He therefore continued to the south-east to get between the enemy and his base.

Sighting of British battle cruisers at 16:54 prompted the deployment at 16:55 of the Aufklarunggruppe (A.G.). The battle cruisers of I.A.G. maintained course to the west to engage to starboard and allow the wind to carry smoke away from the direction of the enemy. The light cruisers of II.A.G. formed up and took station 3 NM ahead. Once the battle cruisers opened fire, the German flotillas took station on the disengaged side.

Since the light forces took only a limited part in the later action, the simplified plot showing only the battle cruisers will be discussed. The Lion opened fire at 17:05, beyond the range of the German guns. I.A.G turned north to close the range, then back to north-east when in effective range. The two lines passed on opposite courses. Once the British had achieved a position between the Germans and their base (to the south-east), they reversed course to the north. Smoke interfered with the fire of the British line, so the formations were changed to line-of-bearing, 3 points to port, and the 2nd BCS was stationed on the port quarter of the 1st BCS. This took some time to achieve, during which the British received significant damage.

The game was ended when damage caused the German line to attempt to break off to the north-east. The time (18:15) was past nightfall for this date, and the code does not currently account for night conditions.
