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.
