Atlantic Convoy

A test game using my Axis & Allies* naval, adapted for hexagons, rules.

It’s a lovely day, so I decided to play a short wargame in the garden.  I have three lightweight trestle tables, each 60 x 100cm and 95cm tall, so I took them from the Shedquarters and set them up on the patio area. I covered them with my somewhat bright blue hexagon cloth, clipped it to the table edges and set to.

Situation.  A convoy of merchant ships, escorted by two British destroyers, is approaching a screen of German submarines in the North Atlantic.

The submarines submerged.  Each is replaced by one real submerged token and 1d6/2 dummies (rounding down).  They all look the same, but the real subs are marked with a number on the bottom and the dummies with a small ‘x’.

Both destroyers have the “Sub Hunter” special rule, so after each German turn, they turn and move 3 hexagons towards the nearest German submarine.  This turn is deducted from their next maximum move.  I decided to change the operation of this rule, see below.

The two destroyers went after the nearest contacts and the convoy was ordered to make best speed, so some of the larger ships increased to maximum speed of 4 hexagons. (around 22 knots)

The entire convoy of 16 merchant ships was now spread over a length of 15 hexagons, or around 3000 yards.

Two submarines closed on HMS Hasty.  One was a dummy, and after declaring its attack was removed from the table.  The other fired a torpedo at the destroyer’s port bow at 1 hex (around 200 yards) range.

Two dice were rolled: 5 and 2.  One hit was scored for the 5.  (4 and 5 score 1 hit, 6 scores 2 hits).  One point of hull damage was caused, and with only one hull point remaining the ship was marked as “crippled”, losing one point from armour, vital armour and speed.

Hasty swung to port and depth-charged the sub, with five dice scoring 6,6,5,4,3 for six hits.  With hull points of 1 and vital armour of 5 the submarine sank immediately.  I decided to adjust the depth charge rule as well (see below).

HMS Herward also depth-charged and sank a submarine with two hits.

Meanwhile Penguin and Countryman, two of the faster ships, both swung to starboard to avoid the destroyers operating in their paths.

The other ships ploughed on at about 12 knots.  One of the cargo ships on the edge of the convoy was struck and began to sink immediately.

The destroyers chased another two targets, both of which turned out to be false contacts.

Three more submarines lined up to attack the convoy but two, on declaring their attack, were revealed as dummies.  The third failed to hit the Atlantic, a large tanker.

Hereward depth-charged another dummy U-boat.  With several wrecks in the process of sinking, ships were now having to take avoiding action to avoid collisions.

Another cargo ship was struck by a torpedo near the centre of the convoy.  She continued, crippled.  Hereward steamed for the location and sank the last of the German submarines.  The convoy proceeded towards Liverpool.

Losses.  One cargo ship lost and one crippled.  HMS Hasty crippled.  Three U-boats sunk.  A good day for the Royal Navy.

Rule changes to be applied.

Depth charges.  Rather than rolling 5 dice for hits on any submarine adjacent to the rear half of the destroyer, I will apply the same system of splitting the dice as I do for gunnery.   Thus the depth charges are thrown in a pattern into the three adjacent hexagons to starboard rear, starboard port and directly astern.  Up to 1/3 of the dice available, rounding up, may be used for each hex, provided that the total number is not exceeded.  

Targeting 5 dice at 1 hex is overkill, because it only needs 1 hit to sink most submarines.  With 1 die there is a 50% chance, with 2 dice a 75% chance and with 5 dice almost 97% chance of rolling 4,5 or 6 on at least one of them.  

Sub Hunter.  Rather than arbitrarily moving the ship at the end of the enemy move, I decided that a destroyer with this special rule must at the start of its turn roll a die and immediately head for the nearest enemy submarine within 1D6 hexagons, notwithstanding any search pattern she is working to.

Summary

All in all a fun little test game, and I think with the rule tweaks the submarines might have a better chance of surviving more than one destroyer sweep.

Three wargames and some real life

Following my recent post “Rethinking my priorities” I have moved the campaign on.
The battle for the Arnhem railway bridge has been fought and the allies now hold this crossing over the Rhine.
I have another game currently in play for this campaign using Memoir ’44 board and rules, but instead of their models I use my own gaming tokens based on German tactical map signs (see photo’ below).
Each token represents one platoon or equivalent.

In this game a German Panzer regiment and a supporting Panzer Grenadier regiment have encountered two battalions of British infantry. They have been fighting for two game hours so far.

On other gaming fronts I have been preparing the battlefield for the long awaited 4th September 1939 battle in my project to refight the whole of World War Two before I die! The troops have been ready for months.

I have also been gathering the models for the first naval encounter of World War Two, the sinking of three commercial vessels by German submarines on 7th September 1939. Although the attacks did not happen in the same area, my game will involve an escorted convoy against three submarines operating independently. British must cross the table with as many ships as possible surviving. German submarines are vying with each other for the maximum ships sunk.

Annoyingly I have lost the box of unpainted “sinking ship” models  that I printed a couple of months ago.   The only one I can find is the half-painted version (now complete) in the centre of the picture below.

I know that if I reprint them they will turn up, so meanwhile the printer is in use to produce dummy submerged submarines for the confusion of friend and foe alike.

My idea for submerged submarines is that when a sub dives it is replaced with a number of transparent models according to the roll of one average die. One of these is marked underneath as the real submarine. They each go their separate ways and until they come into action neither side is allowed to look beneath the model.

I have been struggling with a computer program “Rule the Rail” which is used to design virtual model railway layouts. I found the game in a discount store many years ago and have since upgraded it by downloading extra models and functions provided by other users more clever than me to make it more British and 1950s focussed – my old trainspotting days.

Last week the program suddenly started refusing to save files, although I have successfully run it on Windows 10 for a year or more. I can only guess that Microsoft have updated something to the detriment of my enjoyment. The developers last tested the system with Windows XP, so any fixes are now handled by the fan-base community. I have asked them for help.

My latest, half finished, project is based on a layout found in “Railway Modeller” of the local station where I used to do my trainspotting as a lad in the late ’50s and early ’60s. The actual model is well researched, but the creator admits that it was pure accident that the school-children on the platform are wearing the correct uniform for my old school (Poole Grammar). I want to finish the project, but if I cannot save any changes I am, as they say, “stuffed”.

Incidentally, the developers recently launched a kickstarter to develop this program for the latest PC, Mac and Android operating systems, but it failed with only half a dozen backers. A shame, since there is clearly a large community of users who could have helped.

On a personal note, I have recently undergone a “triple A” investigation for possible aneurism, which showed that I have no problems in that department.  Next Thursday I have my PSA blood test to confirm that all is still well after my cancer operation in November 2017.  Isn’t it amazing how concerned the NHS gets about you when you  are over 60, when so many of the issues could have been solved by better advice when you were 20?
