[Regiment de Grenadiers-à-Cheval de la Garde Impériale]
They became known for their austerity and haughty demeanor.
The army nicknamed them "The Giants", "The Gods" or simply
"The High Heels" from their heavy cavalry, tall boots.

The Guard Horse Grenadiers were the senior regiment in the Guard Cavalry. Their priviledged position the whole army - and even the Guard - had envied. In 1796 the Guard of Directory (Garde du Directoire) was organized and one squadron of Horse Grenadiers was raised. Soon Napoleon enlarged the troop to two and then to four squadrons. The privates wore dark blue coats and collars, white lapels and tall boots. In 1797 they received tall fur caps.

In 1804 the Consular Guard became Imperial Guard. The troopers were quartered at the barracks in the Ecole Militaire where they slept in solid oak beds 6'8" by 4' with a shelf at the head. The food was good and the wine even better. information given.In the very end of the battle of Waterloo, when the entire French army fell apart before the Prussians and the British-Netherland army, the horse grenadiers made a great impression on the pursuers. Captain Barton of the 12th Light Dragoons described how his regiment advanced against the giants on black horses. The grenadiers "appeared to take but little notice of our advance, when opposite their flank they fired a few pistol or carbine shots. We were ... being too weak to make an impression [on them], they literally walked from the field in a most majestic manner."
In November 1815 the regiment was disbanded. On 25 November for the last time their trumpeters sounded the Ban. The standard-bearer advanced to the Inspector and presented the standard. It was the last unit of the whole Imperial Guard (infantry, cavalry, and artillery) disbanded by the Bourbons.
The Guard was no more.
