The field was so cut up by the Adda and the canals of Rittorto and Pendina, that Prince Eugene could make no use of his horse.

If, when master of the bridge of Rittorto, he had been able to charge the French with a body of cavalry, there had been no doubt of his complete success.
After a battle, and in the pursuit of a flying enemy, cavalry is invaluable.

If Napoleon had possessed a suitable number of mounted troops, with an able commander, at the battles of Lutzen and Ligny, the results of these victories had been decisive; whereas they were really without consequence.

On the other hand, the Prussian army in 1806, after the battle of Jena, and Napoleon's army in 1815 at Waterloo, were completely cut to pieces by the skilful use of cavalry in the pursuit of a defeated and dispirited foe.
The want of good cavalry was severely felt in the war of the American Revolution.

Had Washington possessed a few good squadrons of horse, his surprise and defeat in the lines of Brooklyn, and the consequent loss of New York, had never taken place.
