Convoy HX 300
Convoy HX 300 was the 300th of the numbered series of World War II HX convoys of merchant ships from Halifax to Liverpool. It started its journey on 17 July 1944 and was the largest convoy of the war, comprising 166 ships. Background These HX convoys had been established shortly after declaration of war; and the first sailed on 16 September 1939.Hague 2000 pp.126–129 Ships in convoy were less vulnerable to submarine attack than ships sailing independently, but the Allies had difficulty providing an adequate number of escorting warships to establish a protective perimeter for detecting and defeating approaching submarines. British Admiralty operations research scientists evaluating convoy battles of 1941 and 1942 determined losses of ships in convoy were independent of convoy size, but varied with the number of attacking submarines and, when patrol aircraft were unavailable, with the number of escorting warships. They suggested convoy losses could be reduced by 64 percent by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oban
Oban ( ; ' in Scottish Gaelic meaning ''The Little Bay'') is a resort town within the Argyll and Bute council area of Scotland. Despite its small size, it is the largest town between Helensburgh and Fort William. During the tourist season, the town can have a temporary population of up to over 24,000 people. Oban occupies a setting in the Firth of Lorn. The bay forms a near perfect horseshoe, protected by the island of Kerrera; and beyond Kerrera, the Isle of Mull. To the north, is the long low island of Lismore and the mountains of Morvern and Ardgour. Pre-history and archaeology Humans have used the site where Oban now stands since at least Mesolithic times, as evidenced by archaeological remains of cave dwellers found in the town. Just outside the town, stands Dunollie Castle, on a site that overlooks the main entrance to the bay and has been fortified since the Bronze Age. Just to the north of Oban, at Dunstaffnage, excavations in 2010, by Argyll Archaeology, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arctic Convoys Of World War II
The Arctic convoys of World War II were oceangoing convoys which sailed from the United Kingdom, Iceland, and North America to northern ports in the Soviet Union – primarily Arkhangelsk (Archangel) and Murmansk in Russia. There were 78 convoys between August 1941 and May 1945, sailing via several seas of the Atlantic and Arctic oceans, with two gaps with no sailings between July and September 1942, and March and November 1943. About 1,400 merchant ships delivered essential supplies to the Soviet Union under the Anglo-Soviet agreement and US Lend-Lease program, escorted by ships of the Royal Navy, Royal Canadian Navy, and the U.S. Navy. Eighty-five merchant vessels and 16 Royal Navy warships (two cruisers, six destroyers, eight other escort ships) were lost. Nazi Germany's '' Kriegsmarine'' lost a number of vessels including one battleship, three destroyers, 30 U-boats, and many aircraft.

Firth Of Clyde
The Firth of Clyde is the mouth of the River Clyde. It is located on the west coast of Scotland and constitutes the deepest coastal waters in the British Isles (it is 164 metres deep at its deepest). The firth is sheltered from the Atlantic Ocean by the Kintyre peninsula, which encloses the outer firth in Argyll and Ayrshire. The Kilbrannan Sound is a large arm of the Firth of Clyde, separating the Kintyre Peninsula from the Isle of Arran. Within the Firth of Clyde is another major island – the Isle of Bute. Given its strategic location at the entrance to the middle and upper Clyde, Bute played a vital naval military role during World War II. Geography At its entrance, the firth is about wide. At one area in its upper reaches, it is joined by Loch Long and the Gare Loch. This area includes the large anchorage off of Greenock that is known as the Tail of the Bank. (The “Bank” is a reference to the shoal, sandbank and shoal that separates the firth from the estuary of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Loch Ewe
Loch Ewe ( gd, Loch Iùbh) is a sea loch in the region of Wester Ross in the Northwest Highlands of Scotland. The shores are inhabited by a traditionally Gàidhlig-speaking people living in or sustained by crofting villages, the most notable of which, situated on the north-eastern shore, is the Aultbea settlement. History Due to the rugged and inaccessible terrain in which it is located, Loch Ewe has always been an assembly point for maritime trade. Around 1610 the area at the head of Loch Ewe, today known as Poolewe, was urbanised around an iron furnace using charcoal produced in the surrounding woodlands for fuel. English ironmasters found it more economic to ship the ore to Poolewe for smelting than to ship the processed charcoal to England to run furnaces there. The crofting villages which were established in the 1840s, as a result of the local parish's estate being reformed from run-rig to fixed holdings properties, were always quite small.

The campaign peaked from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the German ''Kriegsmarine'' (Navy) and aircraft of the ''Luftwaffe'' (Air Force) against the Royal Navy, Royal Canadian Navy, United States Navy, and World War II United States Merchant Navy, Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces.

Naval Trawler
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some—known in the Royal Navy as "Admiralty trawlers"— were purpose-built to naval specifications, others adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a or gun in the bow equipped the trawler for anti-submarine duties. History Armed trawlers were also used to defend fishing groups from enemy aircraft or submarines. The smallest civilian trawlers were converted to danlayers. Contemporary Some nations still use armed trawlers for fisheries protection and patrol. The Indian Navy used naval trawler ...
