Though breech-loading rifles were, as we have seen, used in the War of Secession, the Prussian army was the first that ever took the field completely armed with such weapons. The Prussian rifle was not new, for it had been invented by a Thuringian gunsmith, named Dreyse, about the time that the Minié rifle appeared. Dreyse’s arm was known as the “zundnadelgewehr,” or needle-gun, and its effect in the Austro-Prussian war was so decisive and startling as to cause muzzle-loading rifles everywhere to be relegated to the limbo of obsolete weapons. Yet the needle-gun was but a sorry weapon in comparison to those now in use, and was distinctly inferior to the Spencer carbine. Its breech mechanism was clumsy, it used a paper cartridge, it was not accurate beyond a range of three hundred yards, and its effective range was scarcely more than twice that distance. The German infantry fought in three ranks, and its tactics was not equal to that employed by the American infantry in the War of Secession. The Prussian field artillery was the most formidable that had yet appeared, and consisted mainly of steel breech-loading rifled guns, which were classed as 6-pounders and 4-pounders, though the larger piece fired a shell weighing fifteen pounds, and the smaller projectile used a shell weighing nine pounds. In the Austrian army the infantry was armed with a muzzle-loading rifle, and the artillery consisted entirely of muzzle-loading rifled guns. The exalted military prestige gained by Prussia rendered it certain that she must soon enter the lists in a contest with France, whose commanding position in Europe was so seriously menaced by the rise of the new power. Foreseeing the inevitable conflict, Napoleon III. endeavored to prepare for a serious struggle. The French infantry was armed with the Chassepôt rifle, which had an effective range nearly double that of the needle-gun. A machine gun, known as the _mitrailleuse_, was also introduced into the French army. Much was expected of these new arms; but so superior was the organization, readiness, generalship, and tactical skill of the Prussians that the war was a practically unbroken series of victories for Prussia and the allied German States. Profiting by their experience in the course of the conflict, the Prussians formed their infantry for attack in three lines; the first consisting of skirmishers, the second of supports, either deployed or in small columns, and the third of a reserve, generally held in column until it came under such fire as to render deployment necessary. The skirmishers were constantly reinforced from the supports, and finally from the reserve as the attack progressed, the whole force being united in a heavy line, and opening the hottest possible fire when close enough to the enemy for the final charge. In its essential principles this attack formation is in use at the present day in the armies of all civilized nations. The Prussian
