Armor was being phased out during the 1500's as muskets capable of penetrating armor proliferated. By the 18th century, hardly any units on the European battlefields wore armor. Except for one - the Cuirassiers. Yet, Cuirassiers do not appear to be common in armies - the British do not have one for example. Common sense however would imply that a cavalryman wearing pistol bullet-stopping armor would obviously be harder to kill than one without.

Is there any information, accounts or otherwise, relating to the advantages/disadvantages a cuirassier has? If the advantages are as heavy, why did armies not use cuirassiers more?

  • No idea if there was much of an advantage, but FWIW cavalry was primarily used to break un-drilled infantry units (a wall of cavalry rushing your way is kind of scary if you're not drilled to stand firm and prepare to receive the charge with a wall of pikes, bayonets, or bullets) and to finish off retreating units so that they don't regroup (in which case you're usually not going to get much resistance).

The advantage of wearing cuirass was obviously protection. As you noted, it could deflect pistol shots, and in theory even muskets at distance. Perhaps the main benefit however, was in fact against other horsemen. Cavalry battles in this period often amounted to individual melee, and like the armour of old, the cuirass offered some defence against enemy sabres.

Of course, protection come at the cost encumbrance. On the battlefield it hinders the soldier's movements in a melee, and burdens the horse's speed, which was critical for the heavy cavalry charge in the age of firearms. Beyond combat concerns, the logistics of finding strong horses adequate for carrying the load was a significant practical and financial headache.

Thus, while the exact trade-offs between armour and flexibility may be a matter of debate, the cumbersomeness of the cuirass was a major complaint from contemporary cavalries. The Marquess of Anglesey, commander of British cavalry in the Peninsular War and later at Waterloo where he famously lost his leg, observed in a post-Waterloo memo that:

I think the Cuirass protects, but it also encumbers, and in a mêlée I am sure the Cuirass causes the loss of many a life.

Likewise, Major North Ludlow Beamish, who served in the Dragoon Guards, noted in his translation of a Württemberg cavalry general's military treatise that:

Armour of any kind is highly objectionable for any cavalry . . . The enormous weight, - the constant clearing required, - the pain which its inflexibility must cause under fatigue, are circumstances which alone qualify its advantages in action . . . there can be no doubt that, however invulnerable a cuirass may render a cavalry soldier, his active properties are thereby much reduced.

Even Napoleon, who relied greatly on his cuirassiers as shock troops, lamented of them that:

One result of having men of large stature, is the necessity of large horses, which doubles the expense and does not render the same service.

Picard, Earnest. "Maxims and Opinions of Napoleon on the Use of Cavalry." Journal of the U.S. Cavalry Association 24:1002

It should be noted that cuirassiers were by no means uncommon during the question's time period. Despite their drawbacks, most if not all the major armies of Europe maintained cuirassiers at some point in the 1700s and 1800s. Their popularity did wax and wane, however as late as 1872, an article in the United Services Magazine noted with some wonder that:

In spite of all these facts and reasoning, the cuirass is still retained in France, Russia, England and Prussia.

"The Future Tactics of Cavalry" United Services Magazine, vol 130, September 1872.

The Austrians were a bit ahead of the curve here, having abandoned the cuirass in 1859. Previously however Austria alone of the major powers maintained cuirassiers through both the French Revolution and the Napoleonic Wars. Most other cavalries had entered the 1700s with cuirassiers, but abandoned them over the course of the century.

Napoleon's success in deploying cuirassiers as shock troops heralded a renaissance (or rather, a last hurrah) for the armoured heavy cavalry. The cuirass thus curiously re-emerged in several armies after Napoleon's defeat. Prussia, having abandoned the armour in 1790, re-equipped her cuirassiers with captured French cuirasses in 1814, as did the Spanish in 1810. The Russians likewise began equipping their heavy cavalry with personal armour in 1812.

Both Prussia and Russia had heavy cavalry that were styled 'cuirassiers', but this reflected tradition rather than equipment. Having abolished the Jurassic in 1790, Prussia only re-adopted it in 1814, while Russia only began to issue body armour in 1812 . . . Spain [formed] its single regiment in 1810, utiliziing cuirasses captured from the French 13e Cuirassiers.

Haythornthwaite, Philip. Napoleonic Heavy Cavalry & Dragoon Tactics. Bloomsbury Publishing, 2013.

Even some minor powers such as Saxony, Warsaw and Westphalia raised some cuirassiers.

The British did actually have cuirassiers too, but they were not styled as such and never saw action wearing them. Three regiments of the Household Cavalry were equipped with steel armour after Waterloo: the 1st and 2nd Life Guards, and the Royal Horse Guards. The irony is observed by the aforementioned Major Beamish:

It is strange that armour should have been given to the British Life Guards immediately after they had proved its inefficiency, - after they, unaided by such defences, had torn the laurels of Waterloo from the cuirassiers of France.

    Napoleon is also recorded expressing dismay at his brother Jerome's decision to equip Westphalian cavalry with the cuirass; at the cost of considerably reducing the total quantity of affordable cavalry. Commented Jan 4, 2018 at 12:29

I'm pretty sure that by that era the cuirassiers were mostly ceremonial. Like the bagpipe playing Scotts in British infantry regiments, they were a leftover from a "more civilised era".

And there are still troops in old fashioned plate armour to this date. They are of course all ceremonial, and tend to put on 21st century uniforms and weapons as needed. Think the Vatican's Swiss guard, the state's only military unit. They were shining armour, halberds, and helmets while on ceremonial guard duty, but have a full arsenal of assault rifles and other modern hardware as well for when and if it comes to an actual armed conflict.

The British guards at Buckingham Palace and other locations are the same, they're in fact rotated on and off that duty between several regular mechanised infantry units among which this ceremonial duty is shared.

While during the late 19th century there might have been units wearing plate armour as a regular part of their combat uniform, this would almost certainly have been a transition era. Remember that even in the Crimean war there were some cavalry charges where the cavalrymen were armed with lances, going up against infantry and artillery armed with rifles and cannon.

    I submit Milhaud's IV Cavalry Corps, 8 regiments strong at Ligny (successful) and Waterloo (unsuccessful), as evidence of functional Cuirassier regiments Commented Jan 4, 2018 at 16:00

The only real advantage of armour is to make the cavalrymen feel safe, to encourage them to charge into infantry armed with gunpowder weapons.

Armour that is thick enough to protect the wearer against guns would have to be too heavy to wear into battle. At best the cuirass can deflect a slow bullet, but it won't do you much good if you charge into infantry with it. However, by making the soldier feel safer it makes them far less likely to chicken out, and this in turn makes success more likely as it would provide complete investment from the soldiers part, and his charges full momentum.

    This is a good base for an answer, but really needs accounts or other sources to provide the information required by OP in the question.
