Evidence

Marlborough now sent his aides-de-camp and staff officers down the whole length of the marching columns with orders to explain to the officers and soldiers of every regiment what he was doing and what had happened, and to tell them that all now depended upon their marching qualities. … In the result Marlborough formed a front beyond the lines, which Villars, arriving piecemeal, was unable to attack. — Winston Churchill, A History of the English-Speaking…, 1378
