Since his arrival at Valtetzi three days before, Petrobey had hardly rested night or day. The ground he had occupied and was fortifying with feverish haste was the top of a large spur of hill, going steeply down into the valley, and commanding a good view of it. Its advantages were obvious, for the cavalry, which at present they were particularly incompetent to meet, could not possibly attack them on such a perch, and also it would be difficult for the Turks to get up any of their big guns, of which there were several in Tripoli, to make an assault. They knew that in that town there were at least ten six-pounders, and certainly fifteen more nine-pounders, though since they had occupied the place, and found that the Turk had made no efforts whatever to bring artillery to bear on them, Petrobey suspected, and as it turned out rightly, that they were not all serviceable. Furthermore, occupying Valtetzi, they cut off Tripoli from Kalamata, whither before long, in all probability, the Turks would send a relief expedition by sea. However, by this occupation of Valtetzi there would be two passes to capture before they could send help to Tripoli, and, as he said, "they will be strong men if they take this."
Tripoli itself lay about eight miles to the northeast, and at present the whole body of Greeks was occupied in fortifying the post they had taken. A village, largely Turkish, had stood on the spot, and the demolition of the houses went on from daybreak to nightfall to make material for building up a defensive wall. The soldiers, meantime, as their barracks were converted into fortifications, substituted for them huts made of poles woven in with osiers and brushwood, similar to those they used on Taygetus. The walls, it must be confessed, presented a curiously unworkmanlike aspect—here and there a course of regular square stones would be interrupted by a couple of Byzantine columns from the mosque, or the capital of a Venetian pillar in which a strange human-faced lion looked out from a nest of conventional acanthus leaves. Farther on in the same row would come a packet of roof tiles plastered together with mud, and a plane-tree standing in the line of the wall was pressed into the service, and supplied the place of a big stone for eight upright courses. Above that it had been sawn off, and the next section of the trunk being straight made a wooden coping for five yards of wall. Here a chimney-pot filled with earth and stones took its place among solider materials; here a hearthstone placed on end, with two inches of iron support for the stewing-pot, staring foolishly out into vacancy. Then came a section where the builders had drawn from a richer quarry, and a fine slab of porphyry and two rosso antico pillars formed an exclusive coterie in the midst of rough blocks of limestone. But though heterogeneous and uncouth, the walls were stout and high, and, as Petrobey said, their business was not to build a pretty harem to please the women.
Inside, a hardy sufficiency was the note. The soldiers' huts, though small, would stand a good deal of rough weather; they were built squarely in rows, camp-wise, and the floors were shingled with gravel from a quarry close by. Two houses only had been kept, in one of which were stored the arms, in the other the ammunition, Petrobey and Nicholas, as before, occupying huts exactly like those tenanted by the common soldiers. The mules and herds of sheep and goats were driven out every morning under an armed escort to pasture on the hills near, and penned to the south of the camp for the night. Food was plentiful, and the men seemed well content, for the booty already taken was very considerable.
In ten days more, before the end of April, the walls were complete, and Petrobey, following out the plan he had formed from the first, sent out daily and nightly skirmishing expeditions, who made unlooked-for raids on the villages scattered on the plain about Tripoli, the inhabitants of which, feeling secure in their neighborhood to the fortress, had not yet sought refuge within its walls. Men, women, and children alike were slain, the valuables seized, the flocks and herds driven up to the camp, and the villages burned. In such operations, inglorious and bloody it is to be feared, but a necessary part of the programme of extermination, which the Greeks believed, not without cause, to be their only chance of freedom, their losses were almost to be numbered on the fingers; once or twice some house defended by a few men inside resisted the attack and fired upon them, in which case the assailants did not scruple to set light to the place; and in ten days more only heaps of smoking ruins remained of the little white villages, which had been dotted among the vineyards like flocks of feeding sheep.
Petrobey also established another small camp on the hills to the east of Tripoli, to guard the road between it and the plain of Argos and Nauplia. They had already intercepted and had a small skirmish with troops coming to that place from Nauplia. The loss on the Greek side was about one hundred; on that of the Turks nearly double, for when it came to hand-to-hand fighting the slow and short-legged Turk was no match for the fresh vigor of the mountain-folk. On this occasion they had lain in ambush on both sides of the road, and opened fire simultaneously at the regiment as it passed. The Turks had with them a contingent of cavalry, but on the rocky and wooded ground they were perfectly useless; and their infantry, leaving the road, had driven the Greeks from their ground, though in the first attack they had lost severely. But this readiness to retreat when necessary, and not waste either powder or lives profitlessly, was in accordance with the policy which Nicholas had indicated, and had been the first to put in practice at Karitaena; and it was exactly this harassing, guerilla warfare, in which cavalry could not be brought into play, in which attack was unexpected and flight was immediate upon any sign of a regular engagement, which made the Turks feel they were fighting with shadows. Though their number at the beginning of the war exceeded those of the Greeks, yet each engagement of the kind lessened them in a far greater proportion than their enemies, who seemed, on the other hand, to be mustering fresh troops every day. Had Petrobey at this period consented to give battle in the plains it is probable that his army would have been wiped out if they had fought to a close, and it says much for his wisdom that he persisted in a policy which was tedious and distasteful to him personally. But the Greeks were acquiring every day fresh experience and knowledge, while the strength of the Turks, which lay in their admirable cavalry and their guns, was lying useless.
In the north, however, affairs had not sped so prosperously. Germanos, who was practically commander-in-chief of the army at Kalavryta—less wise than his colleague at Valtetzi—had risked an attack on the citadel at Patras and suffered a severe defeat. As at Karitaena, a cavalry charge ought to have made him follow Nicholas's example, but he stuck with misplaced bravery to his attempt, until a second body of cavalry took him in the rear and cut off his retreat. With desperate courage his men cut their way through the latter, but a remnant only came through; his loss was enormous compared to that sustained by the Turks, and nothing was gained by it, for the citadel of Patras still remained in the hands of the enemy.
News of this disaster was brought to Valtetzi about the 5th of May, with the information that Turkish soldiers, consisting of eight hundred cavalry and fifteen hundred infantry, had set out eastward along the Gulf of Corinth, under the command of an able Turkish officer, Achmet Bey. Five days afterwards it was reported that they had reached Argos, and next day, while a skirmishing party engaged the Greeks on the hills opposite, the rest of the force passed quietly down the road and reached Tripoli the same evening. It was a splendid achievement boldly and successfully carried out, and Petrobey from that hour held himself in readiness to repel any attack that might be made.
Achmet Bey found Tripoli in a poorer state than the Greeks knew, for their incessant ravages on the plain, their destruction of crops and capture of flocks and herds, as well as the great influx of population, had even now begun to make themselves felt within the walls, for the town and the plain in which it stood were cut off from all assistance, and the plain lay barren and desolate. He saw at once that it was necessary to establish connection with Messenia, for the plain of Argos was occupied by bands of insurgent Greeks, and he had himself scarcely won his way through. Though its port, Nauplia, was still in the hands of the Turks, it also was isolated from connection with the main-land by the insurgents of the plain; and the newly created Greek fleet from the islands of Hydra and Spetzas kept it in a state of semi-blockade by sea, and all provisions were got in with difficulty and consumed in the town. But Achmet Bey, not knowing that Petrobey had established posts on the passes over Taygetus from Kalamata and into Arcadia, thought that a successful attack on Valtetzi would enable them to open regular communication with Messenia, and so with the sea.
It was early on the morning of the 24th of May that the attack was made. At dawn the sentries on the walls of Valtetzi saw a troop of cavalry issue from the southern gate of Tripoli, followed by long columns of infantry, and in a quarter of an hour the camp was humming like swarming bees. Petrobey had established a system of signals with the post on the other side of the valley, but he made no sign to them, for it seemed possible that Achmet, hoping to draw them into the plain, would try to seize the pass they held, which communicated with Argos.
It was a clear blue morning after a cold night, and the troops, defiling from the gate, looked at that distance like lines of bright-mailed insects. First, came the infantry marching in eight separate columns, each containing some five hundred men; next, a long line of baggage-mules, followed by horses pulling two guns; and last, the cavalry on black Syrian horses very gayly caparisoned. Nicholas had an excellent telescope, which he had been given by the captain of an English ship in return for some service, and he and Petrobey watched them until the gates closed again behind.
