Lochnagar Mine
The Lochnagar mine south of the village of La Boisselle in the Somme was an underground explosive charge, secretly planted by the British during the First World War, to be ready for 1 July 1916, the first day on the Somme. The mine was dug by the Tunnelling Companies of the Royal Engineers under a German field fortification known as (Swabian Height). The British named the mine after Lochnagar Street, the trench from which the gallery was driven. The charge at Lochnagar was one of 19 mines that were dug under the German lines on the British section of the Somme front, to assist the infantry advance at the start of the battle. The mine was sprung at on 1 July 1916 and left a crater deep and wide, which was captured and held by British troops. The attack on either flank was defeated by German small arms and artillery fire, except on the extreme right flank and just south of La Boisselle, north of the Lochnagar Crater. The crater has been preserved as a memorial and a religio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Somme
The Battle of the Somme ( French: Bataille de la Somme), also known as the Somme offensive, was a battle of the First World War fought by the armies of the British Empire and French Third Republic against the German Empire. It took place between 1 July and 18 November 1916 on both sides of the upper reaches of the Somme, a river in France. The battle was intended to hasten a victory for the Allies. More than three million men fought in the battle of whom one million were wounded or killed, making it one of the deadliest battles in human history. The French and British had committed themselves to an offensive on the Somme during the Chantilly Conference in December 1915. The Allies agreed upon a strategy of combined offensives against the Central Powers in 1916 by the French, Russian, British and Italian armies, with the Somme offensive as the Franco-British contribution. Initial plans called for the French army to undertake the main part of the Somme offensive, supported on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Cross-section Somme Area
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Eart ...

Russian Sap
Sapping is a term used in siege operations to describe the digging of a covered trench (a "sap") to approach a besieged place without danger from the enemy's fire. (verb) The purpose of the sap is usually to advance a besieging army's position towards an attacked fortification. It is excavated by specialised military units, whose members are often called sappers. By using the sap, the besiegers could move closer to the walls of a fortress, without exposing the sappers to direct fire from the defending force. To protect the sappers, trenches were usually dug at an angle in zig-zag pattern (to protect against enfilading fire from the defenders), and at the head of the sap a defensive shield made of gabions (or a mantlet) could be deployed. Once the saps were close enough, siege engines or cannon could be moved through the trenches to get closer to—and enable firing at—the fortification. The goal of firing is to batter a breach in the curtain walls, to allow attacking infan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnelling Companies Of The Royal Engineers
Royal Engineer tunnelling companies were specialist units of the Corps of Royal Engineers within the British Army, formed to dig attacking tunnels under enemy lines during the First World War. The stalemate situation in the early part of the war led to the deployment of tunnel warfare. After the first German Empire attacks on 21 December 1914, through shallow tunnels underneath no man's land and exploding ten mines under the trenches of the Indian Sirhind Brigade, the British began forming suitable units. In February 1915, eight Tunnelling Companies were created and operational in Flanders from March 1915. By mid-1916, the British Army had around 25,000 trained tunnellers, mostly volunteers taken from coal mining communities. Almost twice that number of "attached infantry" worked permanently alongside the trained miners acting as 'beasts of burden'. From the spring of 1917 the whole war became more mobile, with grand offensives at Arras, Messines and Passchendaele. There was n ...

Battle Of Albert (1916)
The Battle of Albert (1–13 July 1916) is the British name for the first two weeks of British–French offensive operations of the Battle of the Somme. The Allied preparatory artillery bombardment commenced on 24 June and the British–French infantry attacked on 1 July, on the south bank from Foucaucourt to the Somme and from the Somme north to Gommecourt, beyond Serre. The French Sixth Army and the right wing of the British Fourth Army inflicted a considerable defeat on the German 2nd Army but from near the Albert–Bapaume road to Gommecourt, the British attack was a disaster, where most of the casualties of the day were incurred. Against the wishes of General Joseph Joffre, General Sir Douglas Haig abandoned the offensive north of the road to reinforce the success in the south, where the British–French forces pressed forward through several intermediate lines closer to the German second position. The French Sixth Army advanced across the Flaucourt plateau south o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map Commune FR Insee Code 80615
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...
