Operation Nostalgia: HMS Triton attacked by Italian Corvettes

Having resurfaced following it's escape from an attack by a German Arado floatplane, the submarine, HMS Triton sights 3 Italian Corvettes bearing down on them. The weather has turned stormy with a force 7 sea state giving the sub crew confidence that they can successfully evade their attention.

Scale = 1/3000th
Models = Tumbling Dice
Rules = General Quarters 3
Table Size = 4'6" x 3'.

This is another small action but one in which I can further explore the submarine rules in GQ3. On to the action:

The 3 Italian Corvettes in line astern sight the Triton as they are in turn sighted by the sub.

HMS Triton on the surface sights the Italians.

The Italians change their formation to line abreast as they approach the sub. They try a few ranging shots but the range combined with the sea state results in a good deal of inaccuracy. The adverse sea conditions reduces their maximum speed to 15 knots.

The Triton crash dives to periscope depth 

The Triton fires all its 6 forward torpedo tubes in the hope that they may get lucky. It then continues to descend to its maximum operating depth of 250' before running silent.

The Gabbiano observes with alarm the tracks of 3 torpedoes streaking past each side of the ship. They breathe a sigh of relief and press on through the swell.

All 3 Corvettes fail to acquire the sub through their sonar. The weather may have saved them from torpedoes but it is also spoiling their chances of locating their prey. The Gabbiano orders its flotilla to make a port turn through a full 180 degrees hoping for more success on a return run.

The Italians were just about to give up when the Artemide reported a 'ping' 300 yards off it's port bow. It was extremely close!

The Corvettes turn in preparation for making depth charge runs. They successfully maintain contact as the Gabbiano (centre) turns to line up on the sonar hit.

Gabbiano  makes the first attack launching its depth charges from its stern racks. 3 x D12 are rolled. A hit is scored! The sub suffers a battery fire necessitating an immediate surfacing.

As the Triton surfaces it finds itself surrounded by Corvettes. As the crew fight the fire, the deck gun crew surge out onto the deck. They hurriedly prepare to fire the 4" gun.

The heavily pitching ships fire on Triton without success. Similarly the sub's 4" gun crew are unable to score any hits.

After 2 turns the fire still rages in the battery compartment. The Triton desperately tries to fend off the Corvettes and attempts to gain a firing acquisition for its deck tubes. A third turn and once again the firefighting crews attempt to douse the fire without success. The fire now rages through the sub leaving no option but to abandon ship.

The Corvettes pick up the survivors elated by their success.

  1. A serious loss for the Allies! Triton will be sorely missed by the invasion force.

    1. It's certainly not going well for the allies Mike. They need good fortune pretty soon to turn this around.

  2. What a nice little sharp action. I assume under the rules that it was quite possible that this scenario could have ended with the initial torpedoes getting a hit and then the sub not getting detected on that last minute ping?

    1. That's correct Norm. The weather conditions reduced the accuracy of the torps but with the number fired gave the sub a 1 in 3 chance of scoring a hit. The Corvettes did not have hydrophones and were relying on their forward facing sonars. They had initially passed the sub without detecting it and they very nearly failed to detect it again on the return run. Had they failed to do so I was going to call it a day for them. The other hope for the sub being that once acquired, if the Italians lost contact (which happens automatically on the detonation of depth charges) and then failed to re-acquire contact within 3 turns, the sub escapes. They were very lucky to get a dc hit on the first attempt.

  3. Interesting little action. I seem to recall an account of a successful Italian sub-hunter. If memory serves, he had been a submariner himself at one time, so knew how they operated.

    1. Many thanks AP. The Italians often get bad press but the allies lost a fair few subs to Italian vessels. The Corvettes here, although lightly armed, were capable of dumping a fair number of depth charges over a target. When combined with their reasonable sonars they could be a serious threat to any subs.

  4. Yes, definitely the dice Gods have not been favoring the Allies thus far!

    1. I have to say Peter, it is pretty damn frustrating at times! Playing solo you have to overcome the temptation to ignore a dice roll or perform a re-roll when one after another of the allied rolls are poor or the reverse for the Axis forces. e.g. the Gabbiano very nearly scored 3 hits from its depth charges when it should have been lucky to get just the one!

    2. Just started my own campaign for ACW - your whole website a huge inspiration. I read a few pages most weeks. Week 1 turn 1 and a key Union divisional commander got killed while attached to a unit in a firefight. It was a 6 to hit the unit - a 6 for a commander casualty - then 1-2 for a kill (3-6 in this instance injured for ranged fire - capture option in melee also). I rolled 6 - 6 - 1 . He lasts the first week of the civil war and the Union has no trans-mississippi commander. So your comment about the temptation to re-roll poor dice rolls struck a chord. Thats the thing solo - you as much watch a story unfold as "take a side". Brilliant website Jon - I don't think think I would have seen started my campaign or Website without stuff like yours.
