In simplest form, a siege tower was a covered wooden tower on wheels once pushed near the offending wall, a gangplank was dropped to bridge the gap and happy warriors rushed into the town or castle. It was an idea whose time had come, and soon enough all the ancient civilizations had siege towers in their arsenals. At the time, most of the towns in Mesopotamia were surrounded by mud-brick walls, generally sufficient protection against attackers, but the siege towers of the Assyrians allowed them to get over the walls relatively unscathed thus their empire spread virtually unchecked for three centuries. This state of affairs will persist all the way to the Modern Era when airplanes and balloons provide additional ways of attacking cities from outside their defensive perimeters.Ĭlimbing walls up ladders - while the defenders above hurled boiling oil, rocks and pointy objects down - wasn’t conducive to high morale among the troops, and so the Neo-Assyrians invented siege towers around the 9th Century BC. This practically forces attackers to use Catapults and their upgrades once the Renaissance Era hits, since they become the only thing effective against wall-defended cities in the middle game.
#Civilization vi update june 2019 update
The Siege Tower becomes obsolete (cannot be produced anymore) after researching Civil Engineering also, it becomes completely useless when the target civilization develops Urban Defenses.Īfter the June 2019 Update the Siege Tower becomes useless against anything more advanced than Medieval Walls. Note that these two support units do not increase damage at all, but they remove penalties. In the first case, melee units are able to climb over the wall, ignoring it completely, while in the second case they use the ram to ignore the wall's natural strength which protects it from conventional weapons. The Siege Tower is the opposite of the Battering Ram in the sense that units will do major damage to the city and minor damage to the wall, whereas the ram allows major damage to the wall. It affects melee units (and also anti-cavalry units in Gathering Storm). The Siege Tower is the second ancient siege-support unit, along with the Battering Ram. It becomes obsolete after researching Civil Engineering. Only effective against Ancient Walls and Medieval Walls.When adjacent to a city, attacking melee units and anti-cavalry units ignore Walls and immediately assault the city.When adjacent to a city, attacking melee units ignore Walls and immediately assault the city.
