The Austrians had disappeared into the Quadrilateral, where the emperor Francis Joseph assumed personal command, with Hess as his chief of staff. Gyulai had resigned the command of the II. Army to Count Schlick, a cavalry Austrians on the Mincio. general of 70 years of age. The I. Army was under Count Wimpffen. But this partition produced nothing but evil. The imperial headquarters still issued voluminous detailed orders for each corps, and the intervening army staff was a cause not of initiative or of simplification, but of unnecessary delay. The direction of several armies, in fact, is only feasible when general directions (directives as they are technically called) take the place of orders. All the necessary conditions for working such a system—uniformity of training, methods and doctrine in the recipients, abstention from interference in details by the supreme command—were wanting in the Austrian army of 1859. The I. Army consisted of the III., IX. and XI. corps with one cavalry division and details, 67,000 in all; the II. Army of the I., V., VII. and VIII. corps, one cavalry division and details or 90,000 combatants—total 160,000, or practically the same force as the allies. The emperor had made several salutary changes in the administration, notably an order to the infantry to send their heavy equipment and parade full-dress into the fortresses, which enormously lightened the hitherto overburdened infantryman. At this moment the political omens were favourable, and gathering the impression from his outpost reports that the French were in two halves, separated by the river Chiese, the young emperor at last accepted Hess’s advice to resume the offensive, in view of which Gyulai had left strong outposts west of the Mincio, when the main armies retired over that river, and had maintained and supplemented the available bridges.
The possibility of such a finale to the campaign had been considered but dismissed at the allied headquarters, where it was thought that if the Austrians took the offensive it would be on their own side, not the enemy’s, of the Mincio and in the midst of the Quadrilateral. Thus the advance of the French army on the 24th was simply to be a general move to the line of the Mincio, preparatory to forcing the crossings, coupled with the destruction of the strong outpost bodies that had been left by the Austrians at Solferino, Guidizzolo, &c. The Austrians, who advanced over the Mincio on the 23rd, also thought that the decisive battle would take place on the third or fourth day of their advance. Thus, although both armies moved with all precautions as if a battle was the immediate object, neither expected a collision, and Solferino was consequently a pure encounter-battle.
Speaking generally, the battlefield falls into two distinct halves, the hilly undulating country, of which the edge (almost everywhere cliff-like) is defined by Lonato, Castiglione, Cavriana and Volta, and the plain of Medole and Guidizzolo. The Battle of Solferino. village of Solferino is within the elevated ground, but close to the edge. Almost in the centre of the plateau is Pozzolengo, and from Solferino and Pozzolengo roads lead to crossing places of the Mincio above Volta (Monzambano-Salionze and Valeggio). These routes were assigned to the Piedmontese (44,000) and the French left wing (I., II. and Guard, 57,000), the plain to the III. and IV. corps and 2 cavalry divisions (50,000). On the other side the Austrians, trusting to the defensive facilities of the plateau, had directed the II. Army and part of the I. (86,000) into the plain, 2 corps of the I. Army (V. and I.) on Solferino-Cavriana (40,000), and only the VIII. corps (Benedek), 25,000 strong, into the heart of the undulating ground. One division was sent from Mantua towards Marcaria. Thus both armies, though disposed in parallel lines, were grouped in very unequal density at different points in these lines.
The French orders for the 24th were—Sardinian army on Pozzolengo, I. corps Esenta to Solferino, II. Castiglione to Cavriana, IV. with two cavalry divisions, Carpenedolo to Guidizzolo, III. Mezzane to Medole by Castel Goffredo; Imperial Guard in reserve at Castiglione. On the other side the VIII. corps from Monzambano was to reach Lonato, the remainder of the II. Army from Cavriana, Solferino and Guidizzolo to Esenta and Castiglione, and the I. Army from Medole, Robecco and Castel Grimaldo towards Carpenedolo. At 8 A.M. the head of the French I. corps encountered several brigades of the I. Army in advance of Solferino. The fighting was severe, but the French made no progress. MacMahon advancing on Guidizzolo came upon a force of the Austrians at Casa Morino and (as on former occasions) immediately set about deploying his whole corps in line of battle. Meanwhile masses of Austrian infantry became visible on the edge of the heights near Cavriana and the firing in the hills grew in intensity. Marshal MacMahon therefore called upon General Niel on his right rear to hasten his march. The latter had already expelled a small body of the Austrians from Medole and had moved forward to Robecco, but there more Austrian masses were found, and Niel, like MacMahon, held his hand until Canrobert (III. corps) should come up on his right. But the latter, after seizing Castel Goffredo, judged it prudent to collect his corps there before actively intervening. Meantime, however, MacMahon had completed his preparations, and capturing Casa Morino with ease, he drove forward to a large open field called the Campo di Medole; this, aided by a heavy cross fire from his artillery and part of Niel’s, he carried without great loss, Niel meantime attacking Casa Nuova and Robecco. But the Austrians had not yet developed their full strength, and the initial successes of the French, won against isolated brigades and battalions, were a mere prelude to the real struggle. Meanwhile the stern Baraguay d’Hilliers had made ceaseless attacks on the V. corps at Solferino, where, on a steep hill surmounted by a tower, the Austrian guns fired with great effect on the attacking masses. It was not until after midday, and then only because it attacked at the moment when, in accordance with an often fatal practice of those days, the Austrian V. corps was being relieved and replaced by the I., that Forey’s division of the I. corps, assisted by part of the Imperial Guard, succeeded in reaching the hill, whereupon Baraguay stormed the village and cemetery of Solferino with the masses of infantry that had gradually gathered opposite this point. By 2 P.M. Solferino was definitively lost to the Austrians.
During this time MacMahon had taken, as ordered, the direction of Cavriana, and was by degrees drawn into the fighting on the heights. Pending the arrival of Canrobert—who had been alarmed by the reported movement of an Austrian force on his rear (the division from Mantua above mentioned) and having given up his cavalry to Niel was unable to explore for himself—Niel alone was left to face the I. Army. But Count Wimpffen, having been ordered at 11 to change direction towards Castiglione, employed the morning in redistributing his intact troops in various “mutually supporting positions,” and thus the forces opposing Niel at Robecco never outnumbered him by more than 3 to 2. Niel, therefore, attacking again and again and from time to time supported by a brigade or a regiment sent by Canrobert, not only held his own but actually captured Robecco. About the same time MacMahon gained a foothold on the heights between Solferino and Cavriana, and as above mentioned, Baraguay had stormed Solferino and the tower hill. The greater part of the II. Austrian Army was beaten and in retreat on Valeggio before 3 P.M. But the Austrian emperor had not lost hope, and it was only a despairing message from Wimpffen, who had suffered least in the battle, that finally induced him to order the retreat over the Mincio. On the extreme right Benedek and the VIII. corps had fought successfully all day against the Sardinians, this engagement being often known by the separate name of the battle of San Martino. On the left Wimpffen, after sending his despondent message, plucked up heart afresh and, for a moment, took the offensive against Niel, who at last, supported by the most part of Canrobert’s corps, had reached Guidizzolo. In the centre the Austrian rearguard held out for two hours in several successive positions against the attacks of MacMahon and the Guard. But the battle was decided. A violent storm, the exhaustion of the assailants, and the firm countenance of Benedek, who, retiring from San Martino, covered the retreat of the rest of the II. Army over the Mincio, precluded an effective pursuit.
The losses on either side had been: Allies, 14,415 killed and wounded and 2776 missing, total 17,191; Austrians, 13,317 killed and wounded, 9220 missing, total 22,537. The heaviest losses in the French army were in Niel’s corps (IV.), which lost 4483, and in Baraguay d’Hilliers’ (I.), which lost 4431. Of the total of 17,191, 5521 was the share of the Sardinian army, which in the battle of San Martino had had as resolute an enemy, and as formidable a position to attack, as had Baraguay at Solferino. On the Austrian side the IX. corps, which bore the brunt of the fighting on the plain, lost 4349 and the V. corps, that had defended Solferino, 4442. Solferino, in the first instance an encounter-battle in which each corps fought whatever enemy it found in its path, became after a time a decisive trial of strength. In the true sense of the word, it was a soldier’s battle, and the now doubly-proved superiority of the French soldier being reinforced by the conviction that the Austrian leaders were incapable of neutralizing it by superior strategy, the war ended without further fighting. The peace of Villafranca was signed on the 11th of July.
The Campaign of 1866
In the seven years that elapsed between Solferino and the second battle of Custozza the political unification of Italy had proceeded rapidly, although the price of the union of Italy had been the cession of Savoy and Nice to Napoleon III. Garibaldi’s irregulars had in 1860 overrun Sicily, and regular battles, inspired by the same great leader, had destroyed the kingdom of Naples on the mainland (Volturno, 1st-2nd October 1860). At Castelfidardo near Ancona on the 18th of September in the same year Cialdini won another victory over the Papal troops commanded by Lamoricière. In 1866, then, Italy was no longer a “geographical expression,” but a recognized kingdom. Only Rome and Venetia remained of the numerous, disunited and reactionary states set up by the congress of Vienna. The former, still held by a French garrison, was for the moment an unattainable aim of the liberators, but the moment for reclaiming Venetia, the last relic of the Austrian dominions in Italy, came when Austria and Prussia in the spring of 1866 prepared to fight for the hegemony of the future united Germany (see [Seven Weeks’ War]).
The new Italian army, formed on the nucleus of the Sardinian army and led by veterans of Novara and Solferino, was as strong as the whole allied army of 1859, but in absorbing so many recruits it had temporarily lost much of its efficiency. It was organized in four corps, of which one, under Cialdini, was detached from the main body. Garibaldi, as before, commanded a semi-regular corps in the Alpine valleys, but being steadily and skilfully opposed by Kuhn, Gyulai’s former chief of staff, he made little or no progress during the brief campaign, on which indeed his operations had no influence. The main Austrian army, still the best-trained part of the emperor’s forces, had been, up to the verge of the war, commanded by Benedek, but Benedek was induced to give up his place to the archduke Albert, and to take up the far harder task of commanding against the Prussians in Bohemia. It was in fact a practically foregone conclusion that in Italy the Austrians would win, whereas in Bohemia it was more than feared that the Prussians would carry all before them. But Prussia and Italy were allied, and whatever the result of a battle in Venetia, that province would have to be ceded in the negotiations for peace with a victorious Prussia. Thus on the Austrian side the war of 1866 in Italy was, even more than the former war, simply an armed protest against the march of events.
