of the kingship (Diod. XX 73, 1). Antigonos gave Philippos a royal burial at Antigoneia,
but did not allow his grief to interfere with carrying on his business.
Attempts to Eliminate Rivals (306–302 B.C.)
Ptolemy had been a thom in Antigonos's side for a long time, and the crushing defeat
inflicted by Demetrios offered real hope of being able to get rid of him once and for all
if the battle of Salamis were only followed up quickly enough and in sufficient force. In
his letter to Demetrios naming him as co-king, Antigonos summoned his son to meet
him at Antigoneia with a considerable part of his fleet, and, still in 306, a great
expeditionary force was gathered there to march against Egypt: 80,000 infantry,
8,000 cavalry, and eighty-three elephants, and a fleet of 150 warships and 100
transports carrying supplies (Diod. XX 73, 1–2). With these forces Antigonos moved
south through Palestine to Gaza, he himself commanding the army and Demetrios the
fleet, which coasted along with the army. At Gaza he was joined by a great troop of
camels brought to him by some allied Arabs; evidently his relations with the Arab
tribes of the Dead Sea and Sinai regions had improved since 311. The camels were to
carry 130,000 medimnoi of wheat and a large stock of fodder for the animals on the
expedition. The military machines were conveyed in wagons, and in addition there
were the 100 transports of the fleet. With all of this Antigonos expected to reach the
Nile without too much hardship.
Eight days before the setting of the Pleiades (i.e., about October 23rd),
Antigonos ordered his men to take up ten days' ration each and marched from Gaza
towards Egypt, the fleet setting out about midnight of (presumably) the next day
(Diod. XX 73, 3–74, 1). He was taking a risk in setting out so late in the year;
Diodoros tells us that some of the pilots of the fleet were not very happy about it, and
it seems that the admiral Medeios may have advised against it, to judge from a story
in Plutarch of how Medeios is supposed to have dreamed that the expedition would fail
(Dem. 19, 1–2). However, great victories are not won without great risks being taken,
and by waiting until the next spring Antigonos would have lost the chance to
capitalize on Demetrios's victory at Salamis, giving Ptolemy a whole winter in which to
prepare his defenses. Though Antigonos has been blamed by some modern historians
for ignoring "expert" advice (e.g., by

Hornblower, Hieronymus, pp. 219–20), the fact is that despite running into a heavy
storm and losing a few ships, Demetrios and his fleet managed to reach Kasios near
the Egyptian border, ride out the storm, and effect a junction there with Antigonos
and the army (Diod. XX 74, 1–5). Antigonos erred not in ignoring the "experts" who
counseled against the expedition, but in preparing for it on too grand a scale. His
army of 88,000 men, not counting camp followers, was undoubtedly several times
greater than the army Ptolemy could field against him, but, more important, would be
exceedingly difficult to control and maintain unless it proved possible to break across
the Pelousiac branch of the Nile and into Egypt very quickly. Antigonos would have
been better advised to take an army only half the size; this would have been more
manageable and easily maintained, yet probably still far larger than Ptolemy's army.

At any rate, Antigonos safely reached the Nile with his army and fleet and
camped about a quarter of a mile from the river. Ptolemy had already established a
string of loyal garrisons along the Pelousiac branch of the Nile, and he sent out men in
boats to offer large bribes to any soldier of Antigonos who would desert to him. After
the rough march through the desert, many of Antigonos's mercenaries were inclined
to take up Ptolemy's offer, but Antigonos drove off the boats with archers, slingers,
and catapults, and tortured some of the would-be deserters pour décourager les
autres (Diod. XX 74, 5–75,3). Having thereby quelled the desertions for the moment,
Antigonos set in train his plans for forcing a crossing into Egypt. With the knowledge
of Perdikkas's failure in 320, Antigonos was not inclined to try to advance directly
across the river against determined opposition. It was to obviate this that he had
brought a fleet with him: Demetrios was to sail along the coast and effect a landing
behind the Pelousiac mouth of the Nile, thereby turning Ptolemy's defensive position
and enabling Antigonos to cross the river with relative ease. When the ships which
