No man's landNo man's land is waste or unowned land or an uninhabited or desolate area that may be under dispute between parties who leave it unoccupied out of fear or uncertainty. The term was originally used to define a contested territory or a dumping ground for refuse between fiefdoms. In modern times, it is commonly associated with World War I to describe the area of land between two enemy trench systems, not controlled by either side. The term is also used metaphorically, to refer to an ambiguous, anomalous, or indefinite area, in regard to an application, situation, or jurisdiction.
First day on the SommeThe first day on the Somme, 1 July 1916, was the beginning of the Battle of Albert (1–13 July), the name given by the British to the first two weeks of the 141 days of the Battle of the Somme (1 July–18 November) in the First World War. Nine corps of the French Sixth Army and the British Fourth and Third armies attacked the German 2nd Army (General Fritz von Below) from Foucaucourt south of the Somme, northwards across the Somme and the Ancre to Serre and at Gommecourt, beyond, in the Third Army area.
Field artilleryField artillery is a category of mobile artillery used to support armies in the field. These weapons are specialized for mobility, tactical proficiency, short range, long range, and extremely long range target engagement. Until the early 20th century, field artillery were also known as foot artillery, for while the guns were pulled by beasts of burden (often horses), the gun crews would usually march on foot, thus providing fire support mainly to the infantry.
Battle of Vimy RidgeThe Battle of Vimy Ridge was part of the Battle of Arras, in the Pas-de-Calais department of France, during the First World War. The main combatants were the four divisions of the Canadian Corps in the First Army, against three divisions of the German 6th Army. The battle took place from 9 to 12 April 1917 at the beginning of the Battle of Arras, the first attack of the Nivelle Offensive, which was intended to attract German reserves from the French, before the French attempt at a decisive offensive on the Aisne and the Chemin des Dames ridge further south, several days later.
Infiltration tacticsIn warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy frontline strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options.
Race to the SeaThe Race to the Sea (Course à la mer; Wettlauf zum Meer, Race naar de Zee) took place from about 1914 during the First World War, after the Battle of the Frontiers () and the German advance into France. The invasion had been stopped at the First Battle of the Marne (5–12 September) and was followed by the First Battle of the Aisne (13–28 September), a Franco-British counter-offensive. The term describes reciprocal attempts by the Franco-British and German armies to envelop the northern flank of the opposing army through the provinces of Picardy, Artois and Flanders, rather than an attempt to advance northwards to the sea.
Battle of BerlinThe 'Battle of Berlin, designated as the Berlin Strategic Offensive Operation by the Soviet Union, and also known as the Fall of Berlin', was one of the last major offensives of the European theatre of World War II. After the Vistula–Oder offensive of January–February 1945, the Red Army had temporarily halted on a line east of Berlin. On 9 March, Germany established its defence plan for the city with Operation Clausewitz. The first defensive preparations at the outskirts of Berlin were made on 20 March, under the newly appointed commander of Army Group Vistula, General Gotthard Heinrici.
Battle of VerdunThe Battle of Verdun (Bataille de Verdun bataj də vɛʁdœ̃; Schlacht um Verdun ʃlaxt ʔʊm ˈvɛɐ̯dœ̃) was fought from 21 February to 18 December 1916 on the Western Front in France. The battle was the longest of the First World War and took place on the hills north of Verdun-sur-Meuse. The German 5th Army attacked the defences of the Fortified Region of Verdun (RFV, Région Fortifiée de Verdun) and those of the French Second Army on the right (east) bank of the Meuse.
Combined armsCombined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects—for example, using infantry and armour in an urban environment in which each supports the other. According to the strategist William S. Lind, combined arms can be distinguished from the concept of "supporting arms" as follows: Combined arms hits the enemy with two or more arms simultaneously in such a manner that the actions he must take to defend himself from one make him more vulnerable to another.
Trench warfareTrench warfare is the type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. It became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage.
