Trench warfare
Trench warfare has become archetypically associated with the First World War of 1914–1918, when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914. By the end of October 1914 the whole front in Belgium and France had solidified into lines of trenches, which lasted until the last weeks of the war. Mass infantry assaults were futile in the face of artillery fire as well as rapid rifle and machine-gun fire. Both sides concentrated on breaking up enemy attacks and on protecting their own troops by digging deep into the ground. Trench warfare also took place on other fronts, including in Italy and at Gallipoli.
Early modern Britain
The Anglo-Dutch Wars were a series of three wars which took place between the English and the Dutch from 1652 to 1674. The causes included political disputes and increasing competition from merchant shipping. Religion was not a factor, since both sides were Protestant. The British in the first war (1652–54) had the naval advantage with larger numbers of more powerful "ships of the line" which were well suited to the naval tactics of the era.. The British also captured numerous Dutch merchant ships. In the second war (1665–67) Dutch naval victories followed. This second war cost London ten times more than it had planned on, and the king sued for peace in 1667 with the Treaty of Breda. It ended the fights over "mercantilism" (that is, the use of force to protect and expand national trade, industry, and shipping.) Meanwhile, the French were building up fleets that threatened both the Netherlands and Great Britain. In third war (1672–74), The British counted on a new alliance with France but the outnumbered Dutch outsailed both of them, and King Charles II ran short of money and political support. The Dutch gained domination of sea trading routes until 1713. The British gained the thriving colony of New Netherland, and renamed it New York.
