The full offensive value of artillery was not yet understood in any army; and it is not surprising to notice in this campaign the utter absence of the tactics which, in the war with France, brought the German guns almost up to the skirmish line, and kept them actively engaged at close range until the end of the battle. It is, however, amazing to observe the slowness and general inefficiency of the Prussian artillery in every action. At Trautenau, though there were 96 guns belonging to Von Bonin’s corps, only 32 were brought into action, while 42 remained in the immediate vicinity without firing a shot. The remaining 22 guns do not seem to have reached the field at all. At Soor the Austrians brought 64 guns into action; but of the 72 guns of the Prussians, only 18 were brought into action from first to last. At Nachod, Skalitz and Gitschin it is the same story—plenty of Prussian artillery, but only a small portion of the guns brought into action, and those without appreciable effect.
Prince Hohenlohe says that in the entire campaign “the Prussian artillery, which numbered as many pieces as its adversary, had only once been able to obtain the numerical superiority. It had, on all occasions, fought against forces two, three, or even four times superior in number.” At Königgrätz the Prussian artillery was handled with surprising feebleness. The Crown Prince finally succeeded in bringing to bear on the Austrian right a force of artillery superior in numbers to that opposed to him; but, even in this case, his guns accomplished but little. As to the artillery of Frederick Charles, it practically accomplished nothing at all; and it was scarcely of more use on the Bistritz than it would have been in Berlin. From the beginning to the end of the battle, the Austrians had everywhere a decided superiority of artillery fire, except only in the one case on their right.
The Prussian Staff History says, in regard to the engagement south of the Sadowa wood: “A want of unity in the direction of the artillery was painfully evident on this part of the field. Two commandants of regiments were on the spot, but the eleven batteries then present belonged to five different artillery divisions, some of them to the divisional artillery and some to the reserve. This accounts for the want of unity of action at this spot; some batteries advanced perfectly isolated, whilst others retired behind the Bistritz at the same time.” To this Colonel Home adds: “A great deal of this was due to the fact that the guns came into action on one side of a small, muddy, stream, over which there were very few bridges, and across which bridges might have been thrown with ease, while the wagons remained on the other.” It may be further added, that the Prussian artillery seems to have been unduly afraid of encountering infantry fire, and to have had a bad habit of withdrawing to refit and to renew its ammunition. It is said of the Prussian artillery, that “they planted themselves here and there among the reserves, and never found places anywhere to engage.”[22] On the march the artillery was kept too far to the rear, and, owing to its inefficient action, the infantry, long before the close of the campaign, generally showed a disposition to despise its help, and to hurry into action without it, crowding the roads, and refusing to let the guns pass. Much had been expected of their artillery by the Prussians, and its feeble action was a severe disappointment to them. It is to the glory of the Prussians that they were quick to fathom the causes of the inefficiency of their artillery, and that they were able, in four years, to replace the impotence of Königgrätz with the annihilating “circle of fire” of Sedan.
The Austrians far surpassed their adversaries in the skill and effectiveness with which they used their artillery. The superiority of the French artillery had largely contributed to the Austrian disasters in Italy seven years before, and the lesson had not been forgotten. From the beginning of the Campaign of 1866, the Austrian artillery was an important factor in every engagement, and at Königgrätz it was handled superbly. But, in every case, it was used defensively, and the Austrian artillerists originated no new tactical features, and taught no lessons that could not have been learned from Gettysburg, Malvern Hill, Solferino, or even Wagram.
The concentration of the Prussian armies preparatory to hostilities was made partly by marching, and partly by railroad transportation. The work accomplished by the railroads may, perhaps, be best expressed in the words of the Prussian Staff History: “The whole of the marches and of the railway movements were so arranged by the General Staff, in harmony with the railway department, that in their execution, in which both the military and civil powers were concerned, no impediments or delays could occur. The result of these arrangements was, that in the twenty-one days allowed, 197,000 men, 55,000 horses, and 5,300 wagons were transported for distances varying between 120 and 300 miles, without any failure, and in such a manner that they attained the required spots at the very hour requisite.” Prussia was thus enabled, in the short space of three weeks, to place 325,000 men on the hostile frontiers, of which number 267,000 were ready for operations against Austria. Yet, great as this achievement was, it shows that the Prussian military system had not yet reached the perfection shown in 1870, when nineteen days sufficed for the mobilization of an army of 440,000 Germans, and its concentration on the frontier of France.
Further than in the matter of mobilization and concentration, the use of railways in the Austro-Prussian war presented no new features. In the matter of supplying armies in the field, the small area of the theater of war, and the inertness of the cavalry, were such that it is almost impossible to make a comparison of the use of railways in this campaign with the use of the same means of transport in the War of Secession. If we imagine a Prussian army pushing entirely through the Austrian Empire, to the vicinity of Belgrade, and dependent for its supplies on a single line of railway, back to a base on the Prussian frontier; and if we imagine, moreover, that the Austrian cavalry possessed vigilance, enterprise, good firearms and modern ideas, instead of being a mere military anachronism, we can picture a parallel to Sherman’s Atlanta campaign.
In regard to the use of the electric telegraph by the Prussians, Hamley says: “The telegraphic communication between the two Prussian armies invading Bohemia in 1866 was not maintained up to the battle of Königgrätz: had it been, and had the situation on both sides been fully appreciated, their joint attack might have been so timed as to obviate the risk of separate defeat which the premature onset of Prince Frederick Charles’ army entailed.” Yet Hozier describes in glowing terms the equipment of Frederick Charles’ telegraph train, and speaks with somewhat amusing admiration of the feat of placing the Prince’s headquarters, at the castle of Grafenstein, in direct telegraphic communication with Berlin, though the castle was five miles from the nearest permanent telegraph station. With each of the Prussian armies was a telegraph train, provided with the wire and other material requisite for the construction of forty miles of line. Yet, though communication was opened between the Crown Prince and Frederick Charles early on June 30th; though there were three days in which to construct a telegraph line; though the headquarters at Gitschin, Kamenitz and Königinhof could have been put in direct communication without exhausting much more than half the capacity of a single telegraph train, the Prussians neglected even to preserve telegraphic communications to the rear of their armies (and thus with each other via Berlin), and, as we have seen, staked their success upon the safe delivery of a message carried by a courier, over an unknown road, on a night of pitchy darkness. Here again a valuable lesson might have been learned from the Americans.[23]
