Here, then, are our calculations as to the command of the Adriatic at the outset of the war of 1866. They leave out of account only one element—the men, and the spirit of the men. Let us see how the grim realities of war can give the lie to paper estimates.
Wilhelm von Tegethoff, who commanded the Austrian fleet with the rank of rear-admiral, was one of the world's great sailors, and the man for the emergency. He had as a young officer taken part in the blockade of Venice during the revolution of 1848 and 1849; he had seen something of the naval operations in the Black Sea during the Crimean War, as the commander of a small Austrian steamer, and during the war of 1864 he had commanded the wooden steam frigate "Schwarzenberg" in the fight with the Danes off Heligoland. Besides these war services he had taken part in an exploring expedition in the Red Sea and Somaliland, and he had made more than one voyage as staff-captain to the Archduke Maximilian, whose favourite officer and close friend he had been for years. When the Archduke, an enthusiastic sailor, resigned his command of the Austrian fleet to embark for Mexico, where a short-lived reign as Emperor and a tragic death awaited him, he told his brother, the Emperor Francis Joseph, that Tegethoff was the hope of the Austrian navy.
The young admiral (he was not yet forty years of age) had concentrated his fleet at Pola, the Austrian naval port near Trieste. He had got together every available ship, not only the seven ironclads, but the old line-of-battle ship and the wooden frigates and gunboats. The Admiralty at Vienna had suggested that he should take only the ironclads to sea, but he had replied: "Give me every ship you have. You may depend on my finding some good use for them." He believed in his officers and men, and relied on them to make a good fight on board anything that would float, whether the naval experts considered it was out of date or not. Among his officers he had plenty of men who were worthy of their chief and inspired with his own dauntless spirit, and the crews were largely composed of excellent material, men from the wilderness of creek and island that extends along the Illyrian and Dalmatian shores, fishermen and coasting sailors, many of them so lately joined that instead of uniform they still wore their picturesque native costume. The crew looked a motley lot, but, to use Farragut's phrase, "there was iron in the men."
Twenty-seven ships in all, small and large, were moored in four lines in the roadstead of Fasana, near Pola. But they did not remain idly at their anchors. Every day some of them ran out to sea, to fire at moving targets or to practise rapid turning and ramming floating rafts. The bows were strengthened by cross timbers in all the larger ships, and in the target work the crews were taught to concentrate the fire of several guns on one spot. But Tegethoff knew he had not a single gun in his fleet that could pierce the armour of the Italian vessels. He told his officers that for decisive results they must trust to the ram. He had painted his ships a dead black. The Italian colour was grey. "When we get into the fight," said Tegethoff, "you must ram away at anything you see painted grey."
War was declared on 20 June. Tegethoff had been training his fleet since 9 May, and was ready for action. He at once sent out the "Stadion" (a passenger steamer of the Austrian Lloyd line, employed as a scout and armed with two 12-pounders) to reconnoitre the Italian coast of the Adriatic. The "Stadion" returned on the 23rd with news that though war had been expected for weeks the Italian fleet was not yet concentrated. A few of the ships were at Ancona, but the greater part of it was reported to be at Taranto, with Admiral Count Persano, the commander-in-chief, who from the first displayed the strangest irresolution.
Tegethoff was anxious to attempt to engage the division at Ancona before it was joined by the main body from Taranto, but he was held back by orders from his Government directing him to remain in the Northern Adriatic covering Venice. It was not till 26 June that he obtained a free hand within limits defined by an order not to go further south than the fortified island of Lissa.
He left Pola that evening with six ironclads, the wooden frigate "Schwarzenberg," five gunboats, and the scouting steamer "Stadion." He had hoisted his rear-admiral's flag on the "Erzherzog Ferdinand Max."[21] He made for Ancona, and was off the port at dawn next day. The first shots of the naval war were fired in the grey of the morning, when three of the Austrian gunboats chased the Italian dispatch vessel "Esploratore" into the port, outside of which she had been on the look-out. The Austrians were able clearly to see and count the warships under the batteries in the harbour. Besides other craft, there were eleven of Persano's twelve ironclads, the squadron from Taranto having reached Ancona the day before. Only the much-vaunted "Affondatore" had not yet joined.
Tegethoff cleared for action, and steamed up and down for some hours, just beyond the range of the coast batteries. It was a challenge to the Italians to come out and fight. But Persano did not accept it. He afterwards made excuses to his Government, saying he had not yet completed the final fitting out of his ships. The moral effect on both fleets was important. The Austrians felt an increased confidence in their daring leader and a growing contempt for their adversaries. On the 24th the Austrian army, under the Archduke Albert, had beaten the Italians at Custozza, and the Austrian navy looked forward to the same good fortune. The Italians were depressed both by the news of Custozza and the hesitation of their admiral to risk anything.
Early in the day Tegethoff started on his return voyage to Fasana, where he arrived in the evening, and found the ironclad "Hapsburg" waiting to join his flag, after having been refitted in the dockyard of Pola. As there were now persistent rumours that the Italians were going to attempt an attack on Venice, Tegethoff remained in the Fasana roadstead, continuing the training of his fleet. On 6 July he again took it to sea, practised fleet manœuvres under steam, and showed himself in sight of Ancona. But the Italian fleet was still lying idly in the harbour, and Tegethoff once more returned to Fasana in the hope that Persano would attempt some enterprise, during which he would be able to fall upon him in the open.
The Italian admiral was meanwhile wasting time in lengthy correspondence with his Government, and sending it letters which revealed his irresolution and incompetence so plainly that they ought to have led to his immediate supersession. He complained he had not definite orders, though he had been directed to destroy the Austrian fleet, if it put to sea, or blockade it, if it remained in harbour. He explained now that he was mounting better guns in some of his ships, now that he was waiting for the "Affondatore" to join. Once he actually wrote saying that some new ironclads ought to be purchased from other powers to reinforce him. At last he was plainly told that if he did not at once do something for the honour of the Italian navy he would be relieved of his command. With the Austrians victorious in Northern Italy, a raid on Venice would have been too serious an operation, but he proposed as an alternative that a small land force should be embarked for a descent on the fortified island of Lissa, on the Dalmatian coast. His fleet would escort it, and co-operate by bombarding the island batteries. The plan was accepted, and he proceeded to execute it.
