At the Battle of Balaclava, an order reached a brigade of light cavalry to take the Russian guns. The general who sent the order was referring to a small artillery position that had been abandoned. But the commander of the light brigade could not see those guns. He could only see the main Russian battery at the end of the valley. He charged, and the light brigade was cut to pieces. The Charge of the Light Brigade can tell us something pretty interesting about the development of technical communication today.
