Thothmes probably set out on his expedition into Asia in about his sixth or seventh year. He was accompanied by two officers, who had served his father and his grandfather, known respectively as "Aahmes, son of Abana," and "Aahmes Pennishem." Both of them had been engaged in the war which he had conducted against the Petti of Nubia and their Ethiopian allies, and both had greatly distinguished themselves. Aahmes, the son of Abana, boasts that he seven times received the prize of valour--a collar of gold--for his conduct in the field; and Aahmes Pennishem gives a list of twenty-nine presents given to him as military rewards by three kings. It does not appear that any resistance was offered to the invading force as it passed through Palestine; but in Syria Thothmes engaged the Rutennu, and "exacted satisfaction" from them, probably on account of the part which they had taken in the Hyksôs struggle; after which he crossed the Euphrates and fell upon the far more powerful nation of the Naïri. The Naïri, when first attacked by the Assyrians, had twenty-three cities, and as many kings; they were rich in horses and mules, and had so large a chariot force that we hear of a hundred and twenty chariots being taken from them in a single battle. At this time the number of the chariots was probably much smaller, for each of the two officers named Ahmes takes great credit to himself on account of the capture of one such vehicle. It is uncertain whether more than a single battle was fought. All that we are told is, that "His Majesty, having arrived in Naharina" (_i.e._ the Naïri country), "encountered the enemy, and organized an attack. His Majesty made a great slaughter of them; an immense number of live captives was carried off by His Majesty." These words would apply equally to a single battle and to a series of battles. All that can be said is, that Thothmes returned victorious from his Asiatic expedition, having defeated the Rutennu and the Naïri, and brought with him into Egypt a goodly booty, and a vast number of Asiatic prisoners.
