21 January 1942. Hayling Island, England.
Lord Louis Mountbatten, Combined Operations Advisor to the Chiefs of Staff, watched as the Duplex Drive Valiant I* tank ran down the ramp of the new LCT (2). Everyone unconsciously held their breath as the tank transitioned from the ramp to the sea. Nicholas Straussler, the designer of the floatation device that prevented the tank from sinking was standing beside Mountbatten, smiled as the tank moved away from the landing craft obviously under its own power. As it did so a second tank, this time, the light Tetrarch moved to the front of the ramp and followed the larger tank onto the water and headed towards the beach. This was where Mountbatten, Straussler and all the other big wigs were gathered.
It was a cold day, but mercifully quite calm. The two tanks arrived at a depth where they were no longer floating, and the tracks began to bite on the seabed. The Tetrarch managed the incline without too much trouble, but the Valiant I* had obviously found a patch where the tracks couldn’t get enough grip. The tank commander’s solution was to order the driver to back off until they were floating free, then using each track separately to crab the tank over to where the Tetrarch had exited the water and follow it up the beach. Once the two tanks were safely on dry land, the process of dropping the floatation screen was demonstrated, with the tanks then able to fight freely.
Most of the VIPs had seen similar demonstrations, though this was the first having two tanks unload from the single LCT (2). Percy Hobart, under whose overall control these types of vehicles were being developed, was a bit out of sorts. Mountbatten had simply asked what would be the effect of machine gun fire on the tanks as they ran into the shore. Straussler admitted that if the floatation screen was too badly damaged by enemy fire, then the tank would sink. Hobart and Mountbatten hadn’t yet got the measure of each other, and Mountbatten was attempting to rescue the situation with his innate charm, to which Hobart seemed immune.
A second LCT (2) came towards the beach. Onboard was a Valiant I Infantry tank and a Churchill tank that had been adapted for ‘wading’. The hull had been sealed as best as possible, and the engine intake and exhaust had been modified to be well above the level of the hull. When the ramp was lowered the Valiant tank moved forward and seemed almost swamped. The engine however kept going, and the tank gradually managed to make it up the slope. The Churchill tank also successfully made it ashore. The Churchill’s tracks and gearbox dealt with the slope better than that of the Valiant.
Overall, the demonstration had been successful. There were a number of things that would be learned, not least having some kind of clear knowledge of make up of the beach that tanks would land on to see if the ground would be suitable. Mountbatten thought that both ideas were worth pursuing, but worried that the DD tanks would be vulnerable against a defended beach until they were clear of the water and had dropped the floatation gear. Having tanks capable of wading coming off a landing craft meant that the problem of grounding the LCT could be done even if there was still a depth of water between the ramp and dry land.
On the train back later in the day, Mountbatten wrote up some notes. Mr Churchill was pushing as hard as he could for something to be done to relieve the pressure on the Soviets. So far, the limited commando raids had been impressive, but without giving the Germans any real problems. Stalin’s call for a second front was obviously completely unrealistic. The build up of the kind of amphibious ships that would be needed to successfully put a strong force ashore would take years. By summer, if the ships currently out in the Mediterranean were brought back, Mountbatten’s planning team thought that they might, just might, have enough capacity to put the best part of a Division ashore.
The difficulty was that Wavell and Cunningham had persuaded Churchill to allow them to keep those amphibious assets. They planned to use them in a campaign to capture some of the Italian islands, securing the eastern Mediterranean, and prepare to do something about some Greek islands or even Sicily. The 8th Army had plenty of men and tanks sitting around waiting to see what would happen with the French, but capturing Rhodes would be another big loss for Mussolini. The Australian 7 Division had been exercising as much as they could with the commandoes, so there was a solid core for taking the fight across the Mediterranean.
Mountbatten’s problem was not only a lack of the correct shipping, but also an actual Combined Operations organisation that would be able to herd the three cats known as the Navy, Army and RAF. General Alan Brooke was keen on keeping the Prime Minister happy, without actually committing men to a half-baked plan would just end with lots of dead troops with nothing very much to show for it. Helping the Soviets was all very well, but realistically the Infantry and Armoured Divisions currently in the UK weren’t ready to take on the Wehrmacht. O’Connor’s 8th Army in Libya was about the only formation Brooke trusted to do the job. Supporting them, all the way around the Cape of Good Hope was just too long a line of supply for anything more than an island-hopping campaign. Even doing that much would mean some pretty hard lessons would have to be learned.
Lord Louis Mountbatten sometimes wondered if captaining HMS Illustrious would have been the better option. The fact that the Prime Minister, when laying out his plan for Mountbatten to take over Combined Operations, in response to his request to stay with Illustrious the Prime Minister responded “You fool! The best thing you can hope to do there is to repeat your last achievement and get yourself sunk!”. Churchill wanted to take the war to the enemy and saw in Mountbatten a man who would be able to do that. Mountbatten was keen to do his bit, and the exercise that morning gave him another card in his hand.
The ability to support a landing with tanks in the first wave would give the infantry useful support. The difficulties of getting tanks out of the water, up a beach and over any obstacles was still to be satisfactorily resolved. Mountbatten had pencilled in a meeting with Major-General Hobart to discuss just what exactly was in the pipeline and what else should be. The Landing Craft Tank (2) had worked out well, but getting them over the English Channel in anything more than slightly choppy water was a worry. There would probably have to be an American solution to that issue, the ability to build enough ships and smaller craft for an invasion was currently beyond British shipbuilding capacity.
It was Mountbatten’s intention to fly out to Egypt in time to see the planned amphibious attacks that would lead to taking Rhodes. The Australian involvement had meant that the planning had to be absolutely clear on what would happen, the memories of Gallipoli were still very strong among the Australian senior officers. It was probably a godsend that Australian 7 Division were involved from the very beginning. There was a lot of work that was being done in Egypt that Mountbatten wanted to see for himself, and perhaps get a few of the planners back to England with him afterwards.
The danger to all this was in Malaya and Burma. The last big exercise, the dress rehearsal, had had to be postponed because the shipping and the aircraft carrier had to be used to move troops, equipment and fighters from Egypt and Persia to Burma. Once all the ships were back under Cunningham’s command, the exercise would be rescheduled and then hopefully, the offensive to capture enemy held islands could begin.
