Step by step the Hyksos stranger was pushed back to the north-eastern corner of the delta. At length Zoan itself fell into the hands of the Egyptians, and the Hyksos took refuge in the great fortress of Avaris on the extreme border of the kingdom. Here they were besieged by the Theban prince Ahmes, and eventually driven back to the Asia from which they had come. The eighteenth dynasty was founded, and Ahmes entered on that career of Asiatic conquest which converted Canaan into an Egyptian province. At first the war was one of revenge; but it soon became one of conquest, and the war of independence was followed by the rise of the Egyptian empire. Thothmes II., the grandson of Ahmes, led his forces as far as the Euphrates and the land of Aram-Naharaim. The territories thus overrun in a sort of military reconnaissance were conquered and annexed by his son Thothmes III., during his long reign of fifty-four years (March 20, B.C. 1503 to February 14, B.C. 1449). Canaan on both sides of the Jordan was made into a province, and governed much as India is to-day. Some of the cities were allowed still to retain their old line of princes, who were called upon to furnish tribute to the Egyptian treasury and recruits to the Egyptian army. From time to time they were visited by an Egyptian "Commissioner," and an Egyptian garrison kept watch upon their conduct. Sometimes an Egyptian Resident was appointed by the side of the native king; this was the case, for example, at Sidon and Hazor. Where, however, the city was of strategical or political importance it was incorporated into the Egyptian empire, and placed under the immediate control of an Egyptian governor, as at Megiddo, Gaza, Gebal, Gezer, and Tyre. Similarly Ziri-Basana, "the field of Bashan," was under the government of a single khazan or "prefect." The troops, who also acted as police, were divided into various classes. There were the tsabi yidati or "auxiliaries," the tsabi saruti or "militia," the Khabbati or "Beduin plunderers," and the tsabi matsarti or "Egyptian soldiers of the garrison," as well as the tsabi bitati or "house-guards," who were summoned in cases of emergency. Among the auxiliaries were included the Serdani or Sardinians, while the Sute—the Sati or Sitti of the hieroglyphic texts—formed the larger portion of the Beduin ("Bashi-bazouks"), and the Egyptian forces were divided into the cavalry or rather charioteers, and the Misi (called Mas'u in the hieroglyphics) or infantry.

Fragments of the annals of Thothmes III. have been preserved on the shattered walls of his temple at Karnak. Here too we may read the lists of places he conquered in Palestine—the land of the Upper Lotan as it is termed—as well as in Northern Syria. Like the annals, the geographical lists have been compiled from memoranda made on the spot by the scribes who followed the army, and in some instances, at all events, it can be shown that they have been translated into Egyptian hieroglyphs from Babylonian cuneiform. The fact is an indication of the conquest that Asia was already beginning to make over her Egyptian conquerors. But the annals themselves are a further and still more convincing proof of Asiatic influence. To cover the walls of a temple with the history of campaigns in a foreign land, and an account of the tribute brought to the Pharaoh, was wholly contrary to Egyptian ideas. From the Egyptian point of view the decoration of the sacred edifice should have been theological only. The only subjects represented on it, so custom and belief had ruled, ought to be the gods, and the stereotyped phrases describing their attributes, their deeds, and their festivals. To substitute for this the records of secular history was Assyrian and not Egyptian. Indeed the very conception of annalistic chronicling, in which the history of a reign was given briefly year by year and campaign by campaign, belonged to the kingdoms of the Tigris and Euphrates, not to that of the Nile. It was a new thing in Egypt, and flourished there only during the short period of Asiatic influence. The Egyptian cared comparatively little for history, and made use of papyrus when he wished to record it. Unfortunately for us the annals of Thothmes III. remain the solitary monument of Egyptian chronicling on stone.

The twenty-second year of his reign (B.C. 1481) was that in which the Egyptian Pharaoh made his first determined effort to subdue Canaan. Gaza was occupied without much difficulty, and in the following year, on the fifth day of the month Pakhons, he set out from it, and eleven days later encamped at Ihem. There he learned that the confederated Canaanitish army, under the command of the king of Kadesh on the Orontes, was awaiting his attack at Megiddo. Not only were the various nations of Palestine represented in it, but contingents had come from Naharaim on the banks of the Euphrates, as well as from the Gulf of Antioch. For a while Thothmes hesitated whether to march against them by the road which led through 'Aluna to Taanach or by way of Zaft (perhaps Safed), whence he would have descended southward upon Megiddo. The arrival of his spies, however, determined him to take the first, and accordingly, after the officers had sworn that they would not leave their appointed posts in battle even to defend the person of the king, he started on his march, and on the nineteenth of the month pitched his tent at 'Aluna. The way had been rough and impassable for chariots, so that the king had been forced to march on foot.

'Aluna must have been close to Megiddo, since the rear of the Egyptian forces was stationed there during the battle that followed, while the southern wing extended to Taanach and the northern wing to Megiddo. The advanced guard pushed into the plain below, and the royal tent was set up on the bank of the brook of Qana, an affluent of the Kishon. The decisive struggle took place on the twenty-first of the month. Thothmes rode in a chariot of polished bronze, and posted himself among the troops on the north-west side of Megiddo. The Canaanites were unable to resist the Egyptian charge. They fled into the city, leaving behind them their horses and their chariots plated with gold and silver, those who arrived after the gates of the town had been shut being drawn up over the walls by means of ropes. Had the Egyptians not stayed behind in order to plunder the enemy's camp they would have entered Megiddo along with the fugitives. As it was, they were compelled to blockade the city, building a rampart round it of "fresh green trees," and the besieged were finally starved into a surrender.

In the captured camp had been found the son of the king of Megiddo, besides a large amount of booty, including chariots of silver and gold from Asi or Cyprus. Two suits of iron armour were also obtained, one belonging to the king of Kadesh, the other to the king of Megiddo. The seven tent-poles of the royal tent, plated with gold, also fell into the hands of the Egyptians. The catalogue of the spoil was written down on a leather roll which was deposited in the temple of Amon at Thebes, and in it were enumerated: 3401 prisoners and 83 hands belonging to the slain, 32 chariots plated with gold, 892 ordinary chariots, 2041 mares, 191 foals, 602 bows, and 200 suits of armour.

Before the campaign was ended the Egyptian army had penetrated far to the north and captured Inuam, south of Damascus, as well as Anugas or Nukhasse, and Harankal, to the north of the land of the Amorites. All these places seem to have belonged to the king of Kadesh, as his property was carried away out of them. When Thothmes returned to Thebes the quantity of spoil be brought back with him was immense. "Besides precious stones," golden bowls, Phoenician cups with double handles and the like, there were 97 swords, 1784 pounds of gold rings and 966 pounds of silver rings, which served as money, a statue with a head of gold, tables, chairs, and staves of cedar and ebony inlaid with gold, ivory and precious stones, a golden plough, the golden sceptre of the conquered prince, and richly embroidered stuffs. The fields of the vanquished province were further measured by the Egyptian surveyors, and the amount of taxation annually due from them was fixed. More than 208,000 measures of wheat were moreover carried off to Egypt from the plain of Megiddo. The Canaanitish power was completely broken, and Thothmes was now free to extend his empire further to the north.

Accordingly in the following year (B.C. 1479) we find him receiving tribute from the Assyrian king. This consisted of leather bracelets, various kinds of wood, and chariots. It was probably at this time that Carchemish on the Euphrates was taken, the city being stormed from the riverside. Five years later the first part of the annals was engraved on the wall of the new temple of Amon at Karnak, and it concluded with an account of the campaign of the year. This had been undertaken in Northern Syria, and had resulted in the capture of Uarrt and Tunip, now Tennib, to the north-west of Aleppo. No less than one hundred pounds of silver and as many of gold were taken from Tunip, as well as lapis-lazuli from Babylonia, and malachite from the Sinaitic peninsula, together with vessels of iron and bronze. Some ships also were captured, laden with slaves, bronze, lead, white gold, and other products of the Greek seas. On the march home the Egyptian army took possession of Arvad, and seized its rich stores of wheat and wine. "Then the soldiers caroused and anointed themselves with oil as they used to do on feast days in the land of Egypt."

The next year Kadesh on the Orontes, near the Lake of Horns, was attacked and destroyed, its trees were cut down and its corn carried away. From Kadesh Thothmes proceeded to the land of Phoenicia, and took the cities of Zemar (now Sumra) and Arvad. The heirs of four of the conquered princes were carried as hostages to Egypt, "so that when one of these kings should die, then the Pharaoh should take his son and put him in his stead."

In B.C. 1472 the land of the Amorites was reduced, or rather that part of it which was known as Takhis, the Thahash of Genesis xxii. 24, on the shores of the Lake of Merna, in which we should probably see the Lake of Homs. Nearly 500 prisoners were led to Egypt. The Syrian princes now came to offer their gifts to the conqueror, bringing with them, among other things, more than 760 pounds of silver, 19 chariots covered with silver ornaments, and 41 leathern collars covered with bronze scales. At the same time the whole country was thoroughly organized under the new Egyptian administration. Military roads were constructed and provided with posting-houses, at each of which relays of horses were kept in readiness, as well as "the necessary provision of bread of various sorts, oil, balsam, wine, honey, and fruits." The quarries of the Lebanon were further required to furnish the Pharaoh with limestone for his buildings in Egypt and elsewhere.

Two years later Thothmes was again in Syria. He made his way as far as the Euphrates, and there on the eastern bank erected a stele by the side of one which his father Thothmes II. had already set up. The stele was an imperial boundary-stone marking the frontier of the Egyptian empire. It was just such another stele that Hadad-ezer of Zobah was intending to restore in the same place when he was met and defeated by David (2 Sam. viii. 3).
