“It must be remembered,” he goes on to say, “that the balloon would generally be some way behind the first line, and that the enemy would hardly, especially during the heat of battle, pay much attention to it. It is well to remember that if only hit by a few bullets it would not be much damaged, and could be quickly repaired. Both at Frankfort and at Frankenthal the balloons were penetrated by bullets, at the latter place by nine, but the balloon remained up three-quarters of an hour after. In some experiments made at Tours, a balloon was penetrated by bullets at 1,000 yards, but the escape of gas was very slow, and the balloon remained up some time longer.

Secondly—and now comes a case in point which should not be lightly passed over, it is this—

“In 1880 the Siege Operations’ Committee made an experiment at Dungeness with rather more disastrous results for the balloon. An eight-inch howitzer was directed on a captive balloon 2,000 yards off, and 800 feet high. The first shot was unsuccessful, the exact range not being known. The second shell, however, burst just in front of the balloon and tore it open. But even then it took fifteen minutes to descend, so that the aëronauts would have been safe.” Later tests have also taken place.

Many persons would think, and as many more might argue with some show of common sense on their side, that the actual safety of a party of balloonists after their machine had been torn open by a shell from an eight-inch howitzer was perilous in the extreme; but the lecturer had no such fears probably, as he went on with unmoved visage, I daresay, to remark that “bullets made of spongy platinum had been suggested as a means of igniting the hydrogen in a balloon by mere contact.”

But these stirring and well nigh nerve-testing quotations need not be dwelt upon to any further extent, they suffice to show that the risks, without taking into consideration the doings of those horrid torpedoes, have been fairly weighed.

If the dynamiters put in an appearance, and manage by skilful steering to be in at close quarters, then all I have to say is Heaven help those who may be in their power.

While contemplating this all important phase of aërostatics, I sometimes wonder whether these and other equally important ideas have ever entered into the fertile brains of those, whose province it is to lead and direct the military balloon tactics. There are, I have no hesitation in saying, at this critical period of our national history, uses for balloons even in this country, considering its position and possible surroundings, which I could point out if they would be listened to, and which at no distant period may be found unprovided for when most needed.

I recollect when first I talked over with Major Grover, R.E., who went up with me, my plan for using small and large balloons for destructive purposes, I had such a friendly but scathing glance that I at once interpreted his meaning to the effect that “anything of that sort would not be countenanced at head-quarters.”

Well, I have lived to draw attention to the very suggestions which were lightly esteemed a quarter of a century since, but I will not allude to any fresh conceptions at the present time.

Sir Edward Birkbeck, M.P., has done useful service in narrating not long since his experiences with me in the year 1862. Observations for military purposes were gone into, and our ascent made in the presence of His Royal Highness the Prince of Wales and the Duke of Sutherland was narrated with spirit. Instructive comments followed, and war balloons were referred to which have since been spoken of in a pleasing letter, wherein Sir Edward gave evidence that he still has a taste for scientific ballooning.
