Redan

Redan (a French word for "projection", "salient") is a term related to fortifications. It is a work in a V-shaped salient angle toward an expected attack. It can be made from earthworks or other material.

The redan developed from the lunette, originally a half-moon-shaped outwork; with shorter flanks it became a redan.

Redans were a common feature in the coastal batteries built in Malta between 1715 and the end of the 18th century. Surviving batteries with redans include Mistra Battery and Saint Anthony's Battery.

The Russians used redans on their left at the Battle of Borodino against Napoleon. A small redan whose faces make an obtuse angle with a vertex toward the enemy is called a flèche (arrow in French). The Bagration flèches were three redans backwards in echelon. The Shevardino Redoubt (another redan) was erected as an early warning post a mile in front of the Bagration flèches.

A Redan hole or Redan is an aspect of golf course architecture commonly associated with golf architect Charles B. Macdonald. The term alludes to the "Redan" type of fortification. Specifically, a Redan hole has a green which slopes downward and away from the point of entrance, typically the front right portion of the green. Links golf is played on the ground as much as in the air and, consequently, the green slopes away from the golfer playing to the green from the tee or fairway. Thus, it is often played in an indirect manner; that is, the player plays somewhat away from the target and then allows contours to direct the golf ball to its final resting point.
