+++ BATTLE OF THE RIVER PLATE
+++ 13 DECEMBER 1939
+++ SOUTH ATLANTIC RIO DE LA PLATA
This game was played on the International Naval Wargaming Day, the birthday of Fred T. Jane (6 August 1865), the author of Jane‘s Fighting Ships.
After a brief introduction game, the sinking of HMS Rawalpindi we went to the main event, the Battle of the River Plate.
Interestingly the Battle of the River Plate and the fate of HMS Rawalpindi are tied together. The attack on the Northern Patrol was to ease the situation of Admiral Graf Spee. The defiant stand of Rawalpindi was a sensation in the United Kingdom.
Ten surviving crew members of the HMS Rawalpindi were honoured at a special parade on Horse Guards Parade in London on 29 November 1939. The men had recently been rescued from the North Sea and were personally thanked for their bravery by the Second Sea Lord, Admiral Sir Charles Little. Only a few days after they had seen their mates die.
“Whose glorious fight against overwhelming odds deserves the respect and honour of the House and of the nation”
First Lord of the Admiralty, Winston Churchill, addressing Parliament December 1939, famously honouring the heroic and doomed final battle of HMS Rawalpindi.
The attack of the German battleships Gneisenau and Scharnhorst did nothing to alleviate Admiral Graf Spee´s predicament.
On 13 December at 05:20, the British squadron was proceeding on a course of 060° at 14 knots with Ajax at 34°34′S 48°17′W, 390 nmi east of Montevideo. At 06:10, smoke was sighted on a bearing of Red-100, or 320° (to the north-west). Harwood ordered the Exeter to investigate. She swung out of line, and at 06:16, she signalled by lamp: "I think it is a pocket-battleship". Captain Bell ordered Flag N hoisted to the yard arm – "Enemy in sight".
Harwood decided to aggressively close. He signalled “Proceed at utmost speed”, equivalent of a ‘General Chase’ signal, an order to close and kill – not lame – a fleeing enemy.
The rest is history.
We played this battle, ‘captain’ Matthew Belayneh taking on the role of his countryman Henry Harwood, while Andri took the role of Hans Langsdorff.
The battle started pretty straight forward from the initial set up. Some exchanges of salvos took place with minor damage. Matthew tried to close the distance between his Leander-class cruisers and the German pocket-battleship, in hopes of getting within torpedo distance while HMS Exeter used its broadsides. Since the Leander-class HMS Ajax and HMS Achilles had their sterns to the Graf Spee, limiting their fire of the small 6” guns, but also presenting a smaller target.
It was Graf Spee that scored the first heavy salvo, taking out more than a third of the hull points of HMS Exeter.
Next turn Andri had a chance of crippling the Exeter with another such salvo. But no dice, their salvo was ineffective. Now the combined fire of the Royal Navy ships was starting to tell, and HMS Ajax was dangerously close. This turn Andri concentrated his fire on the Ajax and crippled her, taking out all turrets but one.
Captain Matthew won initiative for the turn, and they lined up for engagement. The young captain´s inexperience now showed as he chose to fire first from the crippled Ajax, the brave crew manning the last remaining turret firing a round that just bounced of the armour of the Graf Spee. The he realized that it was now the Graf Spee’s turn to fire before he could use his remaining two ships and a heavy 11” salvo raked the Exeter and crippled it, the Exeter losing all its turrets, now a slow-moving crippled hulk that would not take any further part in the game! HMS Achilles however did manage to cripple the Graf Spee and closed in to use its torpedoes!
Despite being crippled, Graf Spee still had both turrets active and had a reasonable 9 hull points remaining. The Germans won initiative while HMS Achilles ran next to it to let lose its torpedoes. Graf Spee was firing at point blank range at the silhouetted HMS Achilles and let lose a heavy salvo crippling the ship and its valiant crew. However, two turrets remained as well as two torpedoes. Matthew fired both torpedoes and both found their mark. The Graf Spee has no torpedo belt, and the torpedoes did 24 points of damage against the remaining 9 hull points, bringing victory to the Royal Navy.
A victory, despite all the Royal Navy cruisers ending the game crippled!
What a game. There were so many tense all or nothing moments. Had the last torpedo attack failed, the Graf Spee would have made good its escape and with its turrets active it might even have been able to sink one of the enemy ships. For the Royal Navy it was a victory hard won, yet an important one in those dark days.
“The pocket battleship Graf Spee which has been for many weeks preying upon the trade of the South Atlantic, has met her doom. And throughout the vast expanse of water the peaceful shipping of all nations may for a spell at least enjoy the freedom of the seas.”
Winston Churchill – radio broadcast 18 December 1939.
It became a propaganda victory, eclipsing that of HMS Rawalpindi which was soon mostly forgotten.
Historically the Graf Spee was not destroyed this way, Kapitän zur See Langsdorff retreated to Montevideo. There he believed that he was being surrounded by British warships. The reality was the total force comprised the undamaged Cumberland with a full ammunition load, and the damaged Ajax and Achilles with depleted stocks of shells. To reinforce the propaganda effect, these ships, which were waiting just outside the three-mile limit, were ordered to make smoke, which could be clearly seen from the Montevideo waterfront.
The Germans were entirely deceived and expected to face a far superior force on leaving the River Plate. Admiral Graf Spee had also used two thirds of her 283 mm (11.1 in) ammunition and had enough left for approximately only a further 20 minutes of firing.
Ultimately, Langsdorff chose to scuttle his ship in the River Plate estuary on 17 December to avoid unnecessary loss of life for no particular military advantage, a decision that infuriated Adolf Hi**er.
The crew of Admiral Graf Spee were taken to Buenos Aires, Argentina, where Captain Langsdorff shot himself on 19 December. He was buried there with full military honours, and several British officers attended.
---
This invites the question of the action of the two captains, the RN Captain Edward Kennedy og HMS Rawalpindi who decided to put up a hopeless and defiant battle against Gneisenau and Scharnhorst to withhold the centuries of tradition and honour of the Royal Navy.
"We'll fight them both, they'll sink us, and that will be that. Good-bye"
Captain Kennedy
But by his action condemning 237 other crew members to their deaths.
Or Kapitän zur See Langsdorff who decided not to go out guns blazing and chose to scuttle his ship in the River Plate estuary to avoid unnecessary loss of life of his almost 600 crew for no military advantage.
I leave it for you to decide.
