Salamanca, he retreated forty miles in a little more than twelve hours!

In 1814, Napoleon's army marched at the rate of ten leagues a day,
besides fighting a battle every twenty-four hours. Wishing to form a
junction with other troops, for the succor of Paris, he marched his army
the distance of seventy-five miles in thirty-six hours; the cavalry

On his return from Elba, in 1815, his guards marched fifty miles the
first day after landing; reached Grenoble through a rough and
mountainous country, a distance of two hundred miles, in six days, and
reached-Paris, a distance of six hundred miles, in less than twenty

The marches of the allied powers, during the wars of the French

Nevertheless, for a single day the English and Spaniards have made some
of the most extraordinary marches on record.

In 1809, on the day of the battle of Talavera, General Crawford, fearing
