Napata, the royal family, and Governor Raum at its head, turned out to bid farewell to the tumultuous army. Drums beat, bands played, and the army moved, following its traditional order of march and preceded by a force of scouts bearing flags. King Kamose was in the vanguard of the army in the center of a ring of servants, chamberlains, and commanders, followed by the royal guard in elegant chariots. Next came a battalion of chariots, which proceeded rank after rank, further than the eye could see, their wheels sending a deafening squeal into the air, the neighing of their horses like the shrilling of the wind. After these came a battalion of heavy archers with their bows, coats of mail, and quivers of arrows, followed in their footsteps by a battalion of highly trained lancers with their lances and shields. Next was a battalion of light infantry, while the wagons of weapons, supplies, and tents, guarded by horsemen, brought up the rear. At the same time, the fleet, with its huge vessels, set sail, the soldiers that it bore equipped with all the weaponry they might need by way of bows, lances, and swords.
These forces advanced to the music of the band, excitement burning in their youthful, angry hearts, the terrifying sight throwing dread into hearts and minds. They marched all day, eating up the miles, and came to a halt when darkness fell, neither tired nor wearied, seeking help against the hardships of the road and the length of the journey from a resolve that could move mountains. On their way they passed by Semna, Buhen, Ibsakhlis, Fatatzis, and Nafis and they continued to march until they reached Dabod, the last Nubian town. Here the scented breeze of Egypt caressed their faces and they camped and set up their tents to take rest from the privations of the journey and prepare themselves for battle.
The king and his men plotted the first plan of invasion and they plotted it well. Ahmose Ebana, the most skilled man in the whole fleet, was given command of a part of it to take up to the borders of Egypt as though it were a convoy of the sort which the border guards had become accustomed to see pass in recent times. At dawn on the fourth day after the army's arrival at Dabod, the small fleet set sail, reaching Egypt's borders as day was breaking. Ahmose Ebana stood on the deck of the ship in the flowing robes of a trader. He produced the entry permit for the guards and took his fleet safely in. Ahmose knew that the border guard consisted of a few ships and a small garrison, so his plan consisted of taking the ships unawares and overpowering them, then laying siege to the island of Biga until the army and the rest of the fleet could enter Egypt. Thereafter it would be easy for him to strike Sayin before it could prepare itself to resist. The convoy proceeded in open formation and when it drew close to the southern shore of Biga, where the Herdsmen's ships were moored, the soldiers appeared on deck with bows in their hands, while Ahmose, throwing off his trader's cloak, appeared in the dress of an officer and ordered his men to fire their arrows at the men guarding the ships. The fleet approached the moored ships rapidly, swooped down upon them before help could reach them from the shore, and cast nets over them, while the soldiers jumped onto their decks to take possession of them. They clashed with the few guards who were to be found on board in a small battle and crushed them swiftly. During this maneuver, Ahmose's ship fired its arrows at the guards on the bank and prevented the soldiers from coming to the aid of their companions on the ships. Thus, the vessels were quickly subdued without high cost to the attackers and the fleet laid siege to the island to prevent contact with the cities of the north. The Biga garrison took note of the sudden maneuver and rushed to the shore, only to find itself surrounded and imprisoned, its small fleet captive.
The battle was barely over before units of the Egyptian fleet appeared, plowing through the billows on the horizon, its course set straight for the border. This it passed safely without meeting any resistance. Then it joined itself to Ahmose Ebana's fleet, placing the island in the middle of a circle of huge ships and causing the Biga garrison to retreat into its center, out of reach of the arrows of the fleet, which poured down on them from all quarters.
