Despite the relative quietness reigning on a divided Egypt, Kamose become the armed arm of queen Ah-hotep quickly understood that he must react immediately. Because Apophis Aâqenenre, the powerful sovereign of Lower Egypt waited for the next opportunity to seize the frail kingdom of Thebes remained in the hands of a woman and of a child-king.
Kamose also had the sense of the communication. And thanks to the narrations he made of his actions on two big steles and two tablets recovered in Thebes we can partly reconstitute the process of the events of his time :
In spite of the reticences of the counselors of his court appreciating a statu quo with the North ruler who allowed them to live in a relative prosperity in the South, the boiling Theban prince launched in a difficult war of reconquest, submitting firstly the Nubians of Kerma in order to protect Egypt of a possible attack on its South frontier. Then, the Theban army composed of Egyptians, and of Medjaï mercenaries since a long time faithful to Egypt, began his slow progression toward the North, as recalled by this Egyptian text :
"The Horus of Bedhet comes back with his army of a military campaign in Nubia. Re puts him in charge of expulse Seth and his accomplices. After eleven battles begun near Edfu, he repulses the ennemy more and more to the North as far as Sile."
According to his own reports, Kamose attacked the Hyksos on their southern border and destroyed the city of Neferusi 20 km north of Hermopolis, then he took Hardeaï 40 km further north. The Thebans were still at 180 km from Avaris when they intercepted in the western desert a messenger of Apophis asking for help to the king of Kerma, reminding him that in a previous campaign Kamose has already caused great damage to Nubians. This forced Kamose to invest the oases to cut the road to any attempt at encirclement by a junction between the Nubian and Hyksos forces. Finally, he besieged and took the Hyksos capital Avaris after a surprise attack carried out on water by his warships and he triumphantly returned to Thebes, bringing a big booty.
Deceived by the succeeding events some commentators said that Kamose failed to invest Avaris as he had expected and that he died after only eleven years of reign. But thanks to the reports of ancient historians who brought a lot of informations on these troubled times, we make another assumption:
We can think that the legend of Atrides is a greek reflection of the family dramas of the Hyksos sovereigns while Kamose character can be recognized in the Oedipus myth (we will discuss this topic in more details in our chapter "Sistosis - Kermes valiant Heracles ").
By applying the pattern of the Greek legend of Atrids to the character of Egysthe as Kamose (Egyptos), it is clear that when the young Theban ruler having invested the city of Avaris, found himself in front of his enemy Apophis Aa-user-re, the old man had confessed to him that he was his grandfather (and in fact his incestuous father).
Undoubtedly shocked by this revelation, from that moment Kamose joining the camp of his Asian family took the name of Khayan Se-user-en-re, which explains why this name was found in Gebelein near to Thebes with that of Apophis Aa-wser-re and in Kerma with the name of Yakoub-her Mer-wser-re when Apophis was become back a simple Asian prince, while his son Khayan (aka Kamose) still reigned on Upper and Lower of Egypt.
The Jewish historian Flavius Josephus of Roman times reports in his book "Against Apion", Book I, Chapter XIV, 86-87 : "Then the kings of the Thebaid and the rest of Egypt rose up against the Shepherds, began a very long war. Under the king Misphragmuthôsis, the Sphepherds were defeated, he says, driven from the rest of Egypt and were locked in a place with an area of ten thausand arouri: this place was named Avaris. According to Manethon, the Shepherds surrounded it by a big wall, high and strong to safeguard their possessions and their booty. "
The king Misphragmuthôsis obviously can only be Kamose become Khayan after the first siege of Avaris. So he had undertaken this work of fortification to prevent a further attack, because he have decided to keep for him this territory "he reconquered by the strength of his shoulders." That is the reason why he rapidly entered in conflict with his half-brother Ahmose claiming the sovereignty on all the territory of Egypt as the legacy of his dead father Se-qen-re Taa (See the Osirian legend "The conflict between Horus and Seth").
