A one-man midget submarine, the Welman, which was developed in 1941, was used on only one mission as it was thought to be too risky. It was about 20 feet (6.1 m) long and was loaded with a 425-pound (192.8 kg) high explosive charge that could be attached to an enemy warship. In 1942 another small submersible was produced, the Welfreighter, which looked like a boat. It too was loaded with a high explosive charge, as well as mines, but by the time it was ready for action the war was nearly over and it was never used. Similarly, a 12-foot (3.7 m) Motorized Submersible Canoe, which was called ‘Sleeping Beauty’ and was intended to be used by a frogman to carry out reconnaissance or sabotage, also never actually saw action – collapsible canoes tended to be used for such purposes instead. Station XII: Aston House As part of the plan anti-Nazi prisoners-of-war who had been brought to Britain, known as ‘bonzos’, were specially trained for the purpose, although they did not know the real reason behind their training. They would then be parachuted into Germany, thinking their mission was to join resistance fighters and commit acts of sabotage. The hope was that they would be captured by the Gestapo and when interrogated would reveal what was in fact inaccurate and worthless information about their supposed activities. To suggest further the existence of resistance groups, fake wireless messages and equipment such as fake code books would be deliberately allowed to be discovered by the Germans. ConclusionAnti Malaria Malaria is a serious tropical disease spread by mosquitoes. If it isn’t diagnosed and treated promptly, it can be fatal. A single mosquito bite is all it takes for someone to become infected. Symptoms of malaria It’s important to be aware of the symptoms of malaria if you’re travelling to areas where there’s a high risk of the disease. Symptoms include: 1. A high temperature of 38C or above 2. Feeling hot and shivery 3. Headaches 4. Vomiting 5. Muscle pains 6. Diarrhoea Symptoms usually appear between 7 and 18 days after becoming infected, but in some cases the symptoms may not appear for up to a year, or occasionally even longer. When to seek medical attention Seek medical help immediately if you develop symptoms of malaria during or after a visit to an area where the disease is found. You should still seek medical help even if it’s several weeks, months or a year after you return from travelling. If there’s a possibility you have malaria, a blood test will be carried out to confirm whether or not you’re infected. You should receive the results of your blood test on the same day. If you have malaria, treatment will…

With correct yeast handling and storage, reusing yeast can result in significant savings and quality benefits, however to ensure the best results- a yeast food is always recommendable. Following on from which, many flavour defects in beer result from poor yeast health. So making sure your yeast has everything it needs is paramount. Station XVc - 2-3 Trevor Square, Knightsbridge, South Kensington - Camouflage Section, photographic and make-up section. Aston House was the first establishment to experiment with plastic explosive for sabotaging German installations and railways. It also made a range of explosive charges and fuses, including 12 million of the time pencil fuses developed at Station IX, and created a gas-ejecting pen (very James Bond!) and an exploding bicycle pump. Station XV: The Thatched Barn Our Medical Information Service can help with enquiries about this product, for example its appearance, whether you have questions about what it contains, the ingredients in it, or how it works.The Welbike was an ingenious piece of kit that was designed to fit inside a parachute canister. It was a very small, single-seat, folding motorcycle, weighing only 71 pounds (32.2 kg), which could travel at up to 30 miles (48.3 km) per hour, with an amazing range of 90 miles (144.8 km). 3,641 Welbikes were produced and they were used in several major wartime operations throughout the Second World War, as well as by SOE agents. Each tablet also contains 50mg of caffeine, a well-known stimulant which can help to relieve drowsiness. As well as helping to boost your energy, the B vitamins in these tablets have their unique benefits.: Any shoppers that fancy putting Aldi’s spread to the test themselves, can head to stores now to buy Grandessa Mighty Yeast Extractor Marmite.

The administrative headquarters of the SOE were based in and around Baker Street in central London, but to meet the needs of those involved in experimental work, research & development, and training, the Government requisitioned numerous large properties in various parts of Britain. These were identified by numbers – training schools were given Arabic numerals, such as STS 43 (Audley End House in Essex), and experimental establishments were given Roman numerals, such as Station XIV (Briggens in Essex). In total there were about 56 training schools and 17 experimental establishments. Just two of the training schools were in Hertfordshire, but there were eight experimental establishments based in the county. These were:STS 4 - Winterfold, Cranleigh, Surrey - Preliminary School for N (Dutch) and T (Belgian) Sections. From June 1943 became STS 7, Students' Assessment Board (SAB).
