Demonstration (military)

In military terminology, a demonstration is an attack or show of force on a battlefield designed to trick or mislead an enemy. Unlike a feint, a demonstration does not make contact with the enemy. It is usually used as a supporting attack intended to deceive an enemy into thinking the demonstration is the main attack.
An example of a demonstration in the American Civil War was at the Battle of Gettysburg. On July 2, 1863, General Robert E. Lee ordered Lieutenant General Richard S. Ewell to stage a demonstration against Culp's Hill on the Union right flank. This was in support of Lieutenant General James Longstreet's main attack against the Union left flank.
