What is the Abatis field fortification? NATURAL ANTI-TANK OBSTACLES

An abatis, abattis, or abbattis is a anti-tank field fortification consisting of an obstacle formed (in the modern era) of the branches of trees laid in a row, with the sharpened tops directed outwards, towards the enemy. The trees are usually interlaced or tied with wire. Abatis are used alone or in combination with wire entanglements and other obstacles. There is evidence it was used as early as the Roman Imperial period, and as recently as the American Civil War and the Anglo-Zulu War of 1879. A classic use of an abatis was at the Battle of Carillon (1758) during the Seven Years' War. The 3,600 French troops defeated a massive army of 16,000 British and Colonial troops by fronting their defensive positions with an extremely dense abatis. The British found the defences almost impossible to breach and were forced to withdraw with some 2,600 casualties. Other uses of an abatis can be found at the Battle of the Chateauguay, 26 October 1813, when approximately 1,300 Canadian Voltigeurs, under the command of Charles-Michel de Salaberry, defeated an American corps of approximately 4,000 men, or at the Battle of Plattsburgh. batis are rarely seen nowadays, having been largely replaced by wire obstacles. However, it may be used as a replacement or supplement when barbed wire is in short supply. A form of giant abatis, using whole trees instead of branches, can be used as an improvised anti-tank obstacle. Though rarely used by modern conventional military units, abatises are still officially maintained in United States Army and Marine Corps training. Current US training instructs engineers or other constructors of such obstacles to fell trees, leaving a 1 or 2 yards (0.9 or 1.8 m) stump, in such a manner as the trees fall interlocked pointing at a 45-degree angle towards the direction of approach of the enemy. Furthermore, it is recommended that the trees remain connected to the stumps and the length of roadway covered be at least 80 yards (75 m). US military maps record an abatis by use of an inverted "V" with a short line extending from it to the right. Hope you enjoy!! 💰 Want to support my channel?
