  As Thomas Schneider writes:

"Another reign length can be inferred from the note on the verso of the Rhind Mathematical Papyrus whereby in the 11th regnal year of the ruling king, Heliopolis has been conquered, and "he of the South" has attacked and taken Sile.

This is suggested by "a graffito in the quarry at Tura whereby 'oxen from Canaan' were used at the opening of the quarry in Ahmose's regnal year 22."

which followed after the fall of Avaris, this means the reign of Khamudi must have terminated by Year 18 or 19 of Ahmose's 25 year reign at the very latest.

The Hyksos were a foreign line of rulers who invaded Egypt and ruled for several generations before this defeat by Ahmose a native ruler from Thebes, who drove them from Egypt at that time.
