Macdonald continued westward, while, in the other case, nothing could save Kray but the energetic conduct of Hohenzollern’s detachment, which was posted near Reggio. This latter, however, was soon forced over the Po, and Ott, advancing from Cremona to join it, found himself sharply pressed in turn. The field marshal had hoped that Ott and Hohenzollern together would be able to win him time to assemble at Parma, where he could bring on a battle whichever way the French took. But on receipt of Ott’s report he was convinced that Macdonald had chosen the western route, and ordering Ott to delay the French as long as possible by stubborn rearguard actions and to put a garrison into Piacenza under a general who was to hold out “on peril of his life and honour,” he collected what forces were ready to move and hurried towards Piacenza, the rest being left to watch Moreau. He arrived just in time. When after three forced marches the main body (only 26,000 strong) reached Castel San Giovanni, Ott had been driven out of Piacenza, but the two joined forces safely. Both Suvárov and Macdonald spent the 17th in closing up and deploying for battle. The respective forces were Allies 30,000, French 35,000. Suvárov believed the enemy to be only 26,000 strong, and chiefly raw Italian regiments, but his temperament would not have allowed him to stand still even had he known his inferiority. He had already issued one of his peculiar battle-orders, which began with the words, “The hostile army will be taken prisoners” and continued with directions to the Cossacks to spare the surrendered enemy. But Macdonald too was full of energy, and believed still that he could annihilate Ott before the field marshal’s arrival. Thus the battle of the Trebbia (June 17–19) was fought by both sides in the spirit of the offensive. It was one of the severest struggles in the Republican wars, and it ended in Macdonald’s retreat with a loss of 15,000 men—probably 6000 in the battle and 9000 killed and prisoners when and after the equilibrium was broken—for Suvárov, unlike other generals, had the necessary surplus of energy after all the demands made upon him by a great battle, to order and to direct an effective pursuit. The Allies lost about 7000. Macdonald retreated to Parma and Modena, harassed by the peasantry, and finally recrossed the Apennines and made his way to Genoa. The battle of the Trebbia is one of the most clearly-defined examples in military history of the result of moral force—it was a matter not merely of energetic leading on the battlefield, but far more of educating the troops beforehand to meet the strain, of ingraining in the soldier the determination to win at all costs. “It was not,” says Clausewitz, “a case of losing the key of the position, of turning a flank or breaking a centre, of a mistimed cavalry charge or a lost battery . . . it is a pure trial of strength and expense of force, and victory is the sinking of the balance, if ever so slightly, in favour of one side. And we mean not merely physical, but even more moral forces.”
To return now to the Alpine region, where the French offensive had culminated at the end of March. Their defeated left was behind the Rhine in the northern part of Switzerland, the half-victorious centre athwart the Rhine between Mayenfeld and Chur, and their wholly victorious right far within Tirol between Glurns, Nauders and Landeck. But neither the centre nor the right could maintain itself. The forward impulse given by Suvárov spread along the whole Austrian front from left to right. Dessolles’ column (now under Loison) was forced back to Chiavenna. Bellegarde drove Lecourbe from position to position towards the Rhine during April. There Lecourbe added to the remnant of his expeditionary column the outlying bodies of Masséna’s right wing, but even so he had only 8000 men against Bellegarde’s 17,000, and he was now exposed to the attack of Hotze’s 25,000 as well. The Luziensteig fell to Hotze and Chur to Bellegarde, but the defenders managed to escape from the converging Austrian columns into the valley of the Reuss. Having thus reconquered all the lost ground and forced the French into the interior of Switzerland, Bellegarde and Hotze parted company, the former marching with the greater part of his forces to join Suvárov, the latter moving to his right to reinforce the archduke. Only a chain of posts was left in the Rhine Valley between Disentis and Feldkirch. The archduke’s operations now recommenced.
Charles and Hotze stood, about the 15th of May, at opposite ends of the lake of Constance. The two together numbered about 88,000 men, but both had sent away numerous detachments to the flanks, and the main bodies dwindled to 35,000 for the archduke and 20,000 for Hotze. Masséna, with 45,000 men in all, retired slowly from the Rhine to the Thur. The archduke crossed the Rhine at Stein, Hotze at Balzers, and each then cautiously felt his way towards the other. Their active opponent attempted to take advantage of their separation, and an irregular fight took place in the Thur valley (May 25), but Masséna, finding Hotze close on his right flank, retired without attempting to force a decision. On the 27th, having joined forces, the Austrians dislodged Masséna from his new position on the Töss without difficulty, and this process was repeated from time to time in theAction of Zürich. next few days, until at last Masséna halted in the position he had prepared for defence at Zürich. He had still but 25,000 of his 45,000 men in hand, for he maintained numerous small detachments on his right, behind the Zürcher See and the Wallen See, and on his left towards Basel. These 25,000 occupied an entrenched position 5 m. in length; against which the Austrians, detaching as usual many posts to protect their flanks and rear, deployed only 42,000 men, of whom 8000 were sent on a wide turning movement and 8000 held in reserve 4 m. in rear of the battlefield. Thus the frontal attack was made with forces not much greater than those of the defence and it failed accordingly (June 4). But Masséna, fearing perhaps to strain the loyalty of the Swiss to their French-made constitution by exposing their town to assault and sack, retired on the 5th.
He did not fall back far, for his outposts still bordered the Limmat and the Linth, while his main body stood in the valley of the Aar between Baden and Lucerne. The archduke pressed Masséna as little as he had pressed Jourdan after Stokach (though in this case he had less to gain by pursuit), and awaited the arrival of a second Russian army, 30,000 strong, under Korsákov, before resuming the advance, meantime throwing out covering detachments towards Basel, where Masséna had a division. Thus for two months operations, elsewhere than in Italy, were at a standstill, while Masséna drew in reinforcements and organized the fractions of his forces in Alsace as a skeleton army, and the Austrians distributed arms to the peasantry of South Germany.
In the end, under pressure from Paris, it was Masséna who resumed active movements. Towards the middle of August, Lecourbe, who formed a loose right wing of the French army in the Reuss valley, was reinforced to a strength of 25,000 men, and pounced upon the extended left wing of the enemy, which had stretched itself, to keep pace with Suvárov, as far westward as the St Gothard. The movement began on the 14th, and in two days the Austrians were driven back from the St Gothard and the Furka to the line of the Linth, with the loss of 8000 men and many guns. At the same time an attempt to take advantage of Masséna’s momentary weakness by forcing the Aar at Döttingen near its mouth failed completely (August 16-17). Only 200 men guarded the point of passage, but the Austrian engineers had neglected to make a proper examination of the river, and unlike the French, the Austrian generals had no authority to waste their expensive battalions in forcing the passage in boats. No one regarded this war as a struggle for existence, and no one but Suvárov possessed the iron strength of character to send thousands of men to death for the realization of a diplomatic success—for ordinary men, the object of the Coalition was to upset the treaty of Campo Formio. This was the end of the archduke’s campaign in Switzerland. Though he would have preferred to continue it, the Vienna government desired him to return to Germany. An Anglo-Russian expedition was about to land in Holland,[1] and the French were assembling fresh forces on the Rhine, and, with the double object of preventing an invasion of
