The first sight that greets the visitor arriving at the jetty on the opposite shore is the imposing silhouette of the Aphion Class, HMS Alliance, a World War Two veteran British submarine that saw extended service into the early decades of the Cold War; with a modernisation program that greatly reduced her underwater drag profile with the removal of her four inch QF gun and two forward torpedo tubes mounted in the prominent nose bulge seen in the picture of the submarine in 1947 below.
This rebuild together with a new streamlined aluminium hull and fin had the effect of making the vessel faster and quieter underwater.
In 1981 HMS Alliance became the museum vessel she is today, preserved as a memorial to those British submariners who have died in service.

The impression I got on entering the Alliance is the link she forms between the WWII diesel/electric boats and the modern era nuclear powered boats that revolutionised the potential of the submarine into a true submersible able to travel fast and with great endurance without the need to surface on a regular basis.
I have put together a series of pictures to give you an idea of the interior of Alliance starting, as we did, in the bow section with the forward torpedo tubes and the reloads and working towards the stern tubes with the other compartments in between.
After her modernisation and the removal of her external torpedoes, Alliance carried sixteen torpedoes with four 21 inch bow tubes and two stern tubes.
The business end of Alliance was probably the smallest and most cramped compartment on the boat.

The boat has been displayed as set up ready for a cruise with the forward compartment loaded up with provisions to allow the crew to keep going for as long as possible.
The hatch seen below is where supplies and forward compartment torpedoes could be lowered into the vessel.
As we made our way aft we started to pass the first of the crew compartments. HMS Alliance was constructed with a passage way passing along the starboard side with all the compartments given over to the port side, allowing as much space as possible within them.
Here the camera and film collection are rigged up ready for some off watch entertainment.
As well as diesel propulsion, HMS Alliance could propel herself underwater with her two 625 hp electric motors and the hatch below the main passage way was exposed to show the lines of batteries used to store the charge for those motors.
The danger these batteries could present was clearly demonstrated when, in 1971, a battery explosion beneath the crew bunks, whilst Alliance was at Portland, lead to the death of CPO Raymond Kimber who was sadly killed when literally blown out of his bunk

The patterned cushions and youthful portrait of Her Majesty really date the boat to a very particular time and era.
Moving past the crew compartments you arrive at the control centre with periscopes, dive plane controls and all the kit you need to allow HMS Alliance to fight her underwater war back in the day.
Our guides around the boat demonstrated the sounding of the dive klaxon whist downing the lights and switching to red lighting for night time surface cruising. All the WWII submarine movies come to life when looking at these pictures.

As we moved further aft I noticed the first of two hatches, the first,seen below, being an access hatch originally used for the crew of the 4 inch gun.
The Amphion class of submarines were built in the Second World War very much with the war in the Pacific in mind and these submarines are quite a bit larger than the boats designed for the Atlantic and Mediterranean.
During her service in WWII and later the Malayan Crisis, her surface gun was a useful weapon to have to take on unarmed or smaller surface craft, thus saving her torpedoes for the larger enemy ships.

| Probably the most important compartment in terms of crew morale |
These two engines can be seen crammed into the limited space of the engine compartment together with all the controls and instruments needed to manage their use.
On the surface, Alliance could use her diesels to barrel along at 18.5 knots and one can only imagine the noise of these things as she did.
The aft most compartment, rather like the bow, was given over to torpedoes and stores and I was quite happy to step back out into daylight after a very interesting tour, but one that convinced me that if men were meant to go under water we would have been born with gills.
That confirmation was only enhanced as our guide demonstrated the other aspect of this last compartment where the escape hatch was located with its pull down canvass tube arrangement designed to enable the crew to literally pop to the surface when used at a safe depth to make an emergency evacuation.
On chatting to our very helpful guides, both ex-submariners themselves, I was directed to a fenced off area close by where I was told I could find Alliance's old gun stored.

It is perhaps not surprising that Britain with one of the most powerful surface fleets, certainly through modern history, should have been the first navy to be attacked by submarine, a natural weapon of choice to an enemy unable or unwilling to contest in the surface battle.
That first enemy submarine was the Turtle of 1776 and was really the first practical attempt at delivering an attack on a surface warship, in this case HMS Eagle, the 64 gun flagship of the Royal Navy in New York harbour by American Sergeant Ezra Lee during the American War of Independence.

Like all submariners Sergeant Lee was courage personified for simply climbing into this death trap, that alone attempting to fight it and I think Washington's tribute to his courage and skill emphasise the point perfectly.
HMS Holland 1
Jules Verne published 'Twenty Thousands Leagues Under the Sea' in 1870, the classic science fiction novel with the title referring to how far the craft travelled rather than the depth it achieved, rather foretelling the future of modern submarine technology.
Jules Verne's fantastic predictions started to become reality for the Royal Navy when in 1900 it ordered the first of six 'Holland' class boats with the first commissioned in 1901. The Holland 1 is the first of that first group of Royal Navy submarines.
HMS Holland 1
When viewing this submarine it is remarkable to think how quickly these kind of vessels have progressed in the one hundred and seventeen years from this tiny thin skinned riveted Holland 1 to the mighty nuclear powered boats of today.

Rediscovered in 1981 and subsequently raised and restored to the condition she is seen in today the Holland 1 is a very special boat in the history of the British submarine service.
X Class Midget Submarine
Royal Navy X-Craft were midget submarines that were designed to be towed to their area of operation by a mother craft, often a larger submarine, to perform specialist attack and reconnaissance missions that were not possible with conventional size boats.

The other was the reconnaissance missions to the Normandy beaches to allow divers to swim ashore to gather beach samples to determine how stable they would be for allied tanks to cross, to later acting as night-time navigation beacons for the assembly of the landing fleet on D-Day itself.
Operation Postage Able
The weapons carried by X-Craft were the two large side carried explosive panniers containing two tons of amatol explosives in each and designed to be detached under a target vessel to explode on a timer delay to allow the X-Craft to escape.
 |
| One of the explosive panniers can be seen here on the side of the X-24, the only surviving X-Craft |
The endurance of these craft was down to how long the crew could deal with the cramped conditions seen below but was generally considered at about fourteen days.
The submarines would operate initially with a crew of three, commander, pilot and engineer, but would later carry a fourth crew member as diver when performing beach reconnaissance for example.
X-Craft were powered by a 42 hp diesel bus engine, together with a 30 hp electric motor when submerged, giving a maximum surface speed of 6.5 knots and one knot slower when submerged.
'Jolly Roger' Pennants
Submarine crews are the modern day version of the long range raider/cruiser that operate alone on the high seas often in enemy controlled waters, unseen, only betraying their presence when they attack then to disappear into the vastness of the oceans.
Their modus-operandi mimics the pirates of old and the fear and ever present danger of attack that could suddenly develop, a description summed up by First Sea Lord Sir Arthur Wilson who complained in 1901 that submarines were "underhanded, unfair and damned un-English" and that personnel should be hanged as pirates.
Remembering the words of Lord Wilson, Lieutenant Commander Max Horton, commanding HMS E9, which torpedoed the German cruiser SMS Hela ordered the manufacture of a Jolly Roger to be flown on their return to port; with an additional flag to be flown for every other subsequent successful patrol. On realising that they would soon run out of submarine to fly their bunting from, the E9 started to develop symbols to be added to the one flag.
Thus the practice of flying a 'Jolly Roger' after a successful patrol developed among Royal Navy crews during the First World War and became widespread during WWII.

Operation Flagpole - October 1942
The general was tasked with a top secret meeting with French General Charles E Mast to secure Vichy cooperation in the upcoming landings, a mission only partially successful and, given the uncertainty of the loyalties of the Vichy negotiation team members involved, Clark went suitably prepared with his personal M1 carbine.

Chariot Manned Torpedo
A few years ago we spent a very pleasant holiday in Crete in a wonderful villa overlooking the natural harbour of Suda Bay which during WWII was the scene of heavy fighting in May 1941 as German paratroops landed to capture the island from British, Greek and Commonwealth troops.
Raid on Souda Bay
Prior to the landings the Royal Navy was keen to develop Suda as a forward base of operations in the eastern Mediterranean and had based cruisers in the harbour to attack Italian shipping in the area supporting their North African forces.
 |
| The crippled HMS York in Suda Bay after the Italian attack |
The attack left the cruiser HMS York severely crippled afterwards having been hit amidships and would be finished off later by Luftwaffe bombing attacks during the German landings.
The Italian success had much influence on Royal Navy thinking that lead to the development of their own human delivered attack craft or later known as the Chariot human torpedo.

These craft were perhaps not as successful as their Italian counterparts but were yet another way that small underwater craft could penetrate harbour defences to attack enemy ships in harbour.

As well as the WWII collection there is also a very good section in the museum that covers the Post War/Cold War era of submarine developments, but time was drawing our day to a close and I had to quite literally whizz around the last displays before catching the last ferry back to Portsmouth.
As a nod to the modern era collection I will finish my post with a picture of the Tigerfish wire guided acoustic homing torpedo in service with the Royal Navy from 1980 to 2004 and a weapon I was familiar with during its run out in the Falklands War in 1982 and the design faults discovered then which underlined its rather troubled history of development that seems to be one of those weapon design disaster stories that rank alongside the improved Nimrod MRA4 aircraft finally scrapped in the 2010 defence review.
I often think weapons design can be likened to what a horse would look like if designed by committee, namely a camel!

So there we are the final post covering our trips to Portsmouth 2016-2017 with, I hope, an appetite whetting presentation of some of the amazing exhibits on view and to show that Portsmouth and its historic dockyard are well worth a visit if the opportunity presents.
