From the campaign that ended at Megiddo in about 1457 BCE, Thutmose III conducted some seventeen campaigns into Canaan and Syria and instituted a durable imperial system there. Captives were carried to Egypt and assigned to temple estates, royal workshops and agricultural labour, and the annals inscribed at Karnak record them alongside cattle, chariots and metal as part of the spoils dedicated to Amun. A distinct and systematic element was the removal of the sons of Syro-Canaanite rulers to Egypt, where they were raised at court and later returned to govern their inheritances as Egyptianised vassals; Egyptologists read this both as hostage-taking and as a device for producing a loyal client elite. The scale of the transfers is known only from Egyptian royal inscriptions, which enumerate captives in the hundreds and low thousands per campaign but were composed to glorify the king and the god rather than to record numbers accurately.
Thutmose III and his New Kingdom successors campaigned annually in Canaan and Syria, deporting captives to Egypt as temple and estate labour and removing the sons of local rulers to be raised at the Egyptian court
Magen Broshi and Ram Gophna's archaeological survey, which estimates population from excavated settlement area and density coefficients, puts Late Bronze Age Canaan west of the Jordan at roughly 140,000 people, sharply down from the Middle Bronze Age. Egyptian campaign records give captive tallies — the annals of Thutmose III list a few thousand per campaign — that are internally consistent with a region of this size.
No death toll can be given. The Egyptian annals record enemy dead in the low hundreds for individual engagements and emphasise captives taken alive, since living captives were the object of the campaigns; mortality among deportees in transit and in temple labour is undocumented.
Forced labour of captives and the removal of the sons of vassal rulers to the Egyptian court are both described in the Karnak annals and in the Egyptological literature summarised by Britannica.
