At present it was not clearly known which of the two inventors held the palm. The results obtained rendered a just decision difficult. It seemed, however, that in the end armour-plate would have to give way to projectiles. Nevertheless, competent men had their doubts. At the latest experiments the cylindro-conical shots of Barbicane had no more effect than pins upon Nicholl's armour-plate. That day the forger of Philadelphia believed himself victorious, and henceforth had nothing but disdain for his rival. But when, later on, Barbicane substituted simple howitzers of 600 lbs. for conical shots, the captain was obliged to go down in his own estimation. It fact, these projectiles, though of mediocre velocity, drilled with holes and broke to pieces armour-plate of the best metal.
Things had reached this point and victory seemed to rest with the projectile, when the war ended the very day that Nicholl terminated a new forged armour-plate. It was a masterpiece of its kind. It defied all the projectiles in the world. The captain had it taken to the Washington Polygon and challenged the president of the Gun Club to pierce it. Barbicane, peace having been made, would not attempt the experiment.
Then Nicholl, in a rage, offered to expose his armour-plate to the shock of any kind of projectile, solid, hollow, round, or conical.
The president, who was determined not to compromise his last success, refused.
Nicholl, excited by this unqualified obstinacy, tried to tempt Barbicane by leaving him every advantage. He proposed to put his plate 200 yards from the gun. Barbicane still refused. At 100 yards? Not even at 75.
"At 50, then," cried the captain, through the newspapers, "at 25 yards from my plate, and I will be behind it."
Barbicane answered that even if Captain Nicholl would be in front of it he would not fire any more.
On this reply, Nicholl could no longer contain himself. He had recourse to personalities; he insinuated cowardice—that the man who refuses to fire a shot from a cannon is very nearly being afraid of it; that, in short, the artillerymen who fight now at six miles distance have prudently substituted mathematical formulae for individual courage, and that there is as much bravery required to quietly wait for a cannon-ball behind armour-plate as to send it according to all the rules of science.
To these insinuations Barbicane answered nothing. Perhaps he never knew about them, for the calculations of his great enterprise absorbed him entirely.
When he made his famous communication to the Gun Club, the anger of Captain Nicholl reached its maximum. Mixed with it was supreme jealousy and a sentiment of absolute powerlessness. How could he invent anything better than a Columbiad 900 feet long? What armour-plate could ever resist a projectile of 30,000 lbs.? Nicholl was at first crushed by this cannon-ball, then he recovered and resolved to crush the proposition by the weight of his best arguments.
