Take a look and you will see that this balloon was filled with coal gas. that would give approx 1/2 the lift of straigt hydrogen (I've checked the composition - coal gas is approx 50% H2, the rest being mostly methane, and CO (CO is more or less exactly the same molecular weight as N2) - but bearing in mind how small a molecule of H2 is, what would the skin be made of?

That’s over 5½ miles… incredible.
Could it have been of lacquered silk.

The balloon in question was called Mammoth and had a capacity of about 90,000 cubic feet of gas. The skin was constructed from what is described as "American Cloth", which is defined as a cotton cloth, varnished or waterproofed.
The Confederate Army had at least one balloon made of cotton and another made of multi coloured silk, legend has it that the silk was donated from the dresses of Southern ladies, but although the balloon was made from dress silk,the story about donated dresses is untrue.

The French Revolutionary army had used a balloon,successfully,at the Battle of Fleurus in 1794, and had established a Ballon Corps.
Though the advantages of having observers a couple of thousand feet above a battlefield seem obvious,the whole idea was dropped a few years later.[Boney was just a reactionary]

Watching a recent TV documentary about the first airships, Zeppelin constructed his first experimental craft with treated cow guts laminated and sewn into huge bags… these were huge airships and required thousands of animals to be slaughtered… not a happy day for those belonging to the genus of ruminant animals.

Yuk, and I've always fancied travel by airship, Norm, it seemed such a civilised way to get about. Our old bar, the drifting, discursive dirigible was proof of that.

Napoleon was also very progressive in that he appointed a woman, Mme Sophie Blanchard, as air service chief - her exact title and position isn't clear but she was his principal balloon advisor for the proposed invasion of England when he seriously considered using fleets of troop carrying balloons. (She said, correctly, that the proposed aerial attack idea would probably fail because of the prevailing wind direction). Mme Blanchard had become Napoleon's chief balloonist, "Aéronaute des Fêtes Officielles", in 1804 when she replaced another balloon pioneer André Jacques Garnerin after he had disgraced himself by failing to control the balloon that had been launched in Paris to mark the emperor's coronation. The balloon had eventually drifted half way across Europe and crashed in Rome where it became the subject of many jokes at Napoleon's expense.
After her husband died in 1809 following a ballooning accident, Mme Blanchard made a name for herself as an accomplished solo balloonist giving demonstrations and displays all over Europe. Her speciality was night flights during which she launched rockets from her balloon and dropped baskets of fireworks attached to parachutes. With hindsight one feels that combining hydrogen-filled balloons and fireworks would almost inevitably lead her to a violent end. True enough her last performance was over the Tivoli gardens in Paris when her hydrogen balloon caught fire while she was launching pyrotechnic flares, and she fell to her death. But she certainly went out with a bang.

Indeed they don't... but isn't that partly because, the lady aéronaute in question had a nasty accident during filming the ad (if I remember she lost control and crashed into a cliff) and successfully sued (the PR comp I guess) for many, many thousands since she was thereafter confined to a wheelchair? If I'm correct I guess she ain't so Nimble any more, poor lass.

I never knew that, Meles.
A balloon or two might have been useful for the Emperor at Waterloo.

Not sure whether to put this here on in The Magnificent Men and their Flying Machines but I read that a dirigible is a balloon that can be pointed in a direction hence the name. The odds and ends I've looked at intermittently regarding Charlemagne - and Lotharingia - led me to the information that one Jacques Trolley de Prevaux flew a dirigible over part of what used to be Lotharingia with a cameraman taking a film of the devastation of World War I. The clip I'm linking is a view of Ypres. The information about the video says the film was made in 1919. I searched Res Hist and couldn't see that the clip had been posted before but as ever apologies if it has been referenced previously and my search didn't cut the mustard.
