Scarborough Raid, December 1914

In December of 1914, the High Sea Fleet (HSF) sortied in support of a bombardment of the English coast by the 1st Scouting Group. Alerted by Room 40, the Admiralty ordered the 2nd Battle Squadron, the 3rd Cruiser Squadron, the 1st Light Cruiser Squadron and the Battle Cruiser Squadron to trap what they thought was a raid by the 1st Scouting Group alone. Bad weather, along with tactical choices and signaling errors prevented a major clash. See, for example, References 1 and 2.

This scenario uses an assumption of better weather to examine a potential engagement between the British force and the HSF near dawn on December 16th. Potential encounters which might have occurred if the High Sea Fleet had not turned back during the night are ignored. The 1st Scouting Group is near the coast at dawn and too distant to be involved. The battle is between Warrender (with Beatty under his command) and Ingenohl. For this date and latitude, nautical twilight begins at 0659 hrs (GMT) and sunrise is at 0825 hrs.

The orders of battle are listed in the narrative file:

Approach to contact and deployment (0825-0900 hrs)

The initial cruising formations are taken from Reference 3, Charts 5 and 7. The HSF has turned south after reaching its rendezvous position (labeled as “700 Uhr-Punkt” on Reference 3, Chart 8). The British force has reversed course to the north after passing the cleared minefield lane leading east toward the coast.

When the armored cruisers in the screen of the HSF (Roon and Prinz Heinrich) are sighted, the British force deploys to starboard (0825 hrs). The withdrawal of the British light cruiser squadron to its battle position prevents it from sighting more of the enemy, and it is left to Beatty to report the leading ships of the HSF battle line 23 minutes later (0848 hrs). The (historical) British night cruising formation had the armored and light cruisers in compact columns and not spread out in a search screen. It may have been doctrine to do this only after sunrise. In the actual action, the light cruisers were spread out by 0900 hrs and the armored cruisers by about 1200 hrs (Reference 3, Chart 11, times adjusted to GMT).

The HSF deploys to port at 0835 hrs, based on sighting the British battle cruisers, now about 4 NM ahead of the British battleships. The battleships are not sighted until 0852 hrs (and not engaged until 0903 hrs), so the HSF maneuvers in this phase are based mainly on engaging the battle cruisers.

Main action and disengagement (0900 – 0940 hrs)

Only battleships and battle cruisers are plotted in this phase for clarity.

Heavy damage to the Lion forces her to turn away at 0902 hrs, but it is too late, and she sinks at 0903 hrs. Tiger is also heavily damaged, but leads the remaining battle cruisers to the NE until her reduced speed causes Queen Mary to take the lead . Since the loss of the Lion is clearly visible to Warrender in the King George V, and since the entire HSF is now known to be present, control of the British side by the AI code was stopped and a withdrawal southward was ordered at 0905 hrs. The AI code does not yet have algorithms to decide on a general withdrawal. All units were ordered to make funnel smoke.

The HSF battle line attempts to maintain the current range by reversing course, but not realizing that the enemy is in flight, makes the turn to starboard, i.e., away from the action. It is not until 0920 hrs that the HSF turns to the SE. This allows the British to get out of range. The British are slightly faster and most would have escaped in any case, but an earlier turn to the south by the HSF might have destroyed the Tiger, then only capable of 18 knots.

Status at the end of the game:

This (admittedly contrived) scenario shows the difficulty of destroying Warrender’s outnumbered force with a HSF consisting largely of slower heavy ships. The advance of the Battle Cruiser Squadron several miles ahead of the 2nd Battle Squadron, while it resulted in the loss of the Lion, allowed the battleships to escape before being significantly damaged.

This diecast 1:160 scale model was modified to roll (unmotorized) on my N-gauge layout. Engine and tender wheels were replaced with Arnold and Micro-trains, respectively. The engine chassis required some modification, and the result is less than perfect. Both engine and tender have too much friction. The Kato motorized car can move it with enough voltage, but not reliably through points.

1905 Battle of Singapore

This scenario is a fictional battle where the British attempt to stop the 2nd Pacific Squadron from reaching its destination in 1905. The idea for the game came from this blog post with a memo by the Director of Naval Intelligence, Prince Louis of Battenberg, which includes the proposed British force to be assembled at Singapore:
Since the memo’s proposed location for the battle (west and south-west of the Straits of Sunda) assumed that the 2nd Pacific Squadron would not go through the Straits of Malacca as it did, the location has been moved to the open water between Singapore and the Island of Borneo.

With the exception of the 4 “Duncans” from Mediterranean, the memo does not list specific ships. The order of battle for the game attempts to reconcile the memo with the fleet deployments listed here:
The two ‘PARTIALLY-ARMOURED CRUISERS’ from the China station are taken to be the protected cruisers of the Powerful class, although they may have been the Amphitrite and Argonaut of the Diadem class. The latter class is not yet included in the game code. The British third class cruisers are not included.

The code AI ran both side’s forces.

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

Force reports:

Plots and commentary:
The 2nd Pacific Squadron cruising formation is that of the Battle of Tsushima. The formation is compact, with no screening or scouting ships. This is consistent with the intent to pass north unobserved. The British force (dubbed the Far East Fleet) cruising formation has two battleship divisions in line ahead, the armoured cruiser division stationed ahead, two divisions of cruisers in a screen ahead and the destroyer flotilla stationed abeam to starboard of the flagship Duncan. The wide scouting screen is deployed to assist in finding the opposing force.
After the initial sightings, the Far East Fleet alters course to close the range. The 2nd Pacific Squadron deploys to port to gain a downwind position. The Far East Fleet later deploys to starboard to engage the enemy battleline.

Once the battle lines open fire, the 2nd Pacific Squadron reverses direction to the south to engage on parallel courses. Since visibility is good and the torpedos carried by the destroyers are short-ranged, the flotillas remain out of action on the disengaged sides of the battlelines.

This simplified plot omits all but the battleships for clarity. Few hits are obtained until ranges fall below about 8,000 yards. As the range continues to decrease, hits from both primary and secondary batteries shatter the leading battleship divisions of both sides. The four Duncan class are sunk (one blows up) and the four Borodino class are damaged. At this point it was assumed that the fleets would disengage.

This plot shows the entire engagement.

End of game status:
The damage to the best ships of the 2nd Pacific Squadron would seem to make it pointless to continue toward Vladivostok, so the British objective was achieved.

Memories and Thoughts of an Old Warship Builder (WW1 Era)

Thanks to a link provided by a post in the NavWeaps Forum “Battleship Vs Battleship”, I was able to obtain a short document written by a WW1 era German warship design engineer, Hans Bürkner. It discusses his career and some of the technical choices made from about 1905 until the end of the war.

Since I can’t read much German, I used OCR software to convert the document to a text format, edited the German text to correct errors in recognizing the Gothic font, used Goggle translate to generate English text and edited the English text, as much as I was able, to use more common naval language. There are still some areas where I am uncertain of the meaning. The NavWeaps post linked above translates of some of the more important technical information, probably more accurately than I did.
