102,2). To further his aim of surprise, Demetrios tarried at Kenchreai for several
days, engaged on various sorts of pleasurable pursuits, while covertly preparing his
attack. He apparently established a squadron of ships in the Gulf of Korinth, for when
he was ready, he ordered some ships to sail by night to attack the harbor of Sikyon,
while mercenaries under his officer Diodoros were in the same night to march around
Sikyon and attack from the west along the Pellene road, and he himself led an attack
from the east (Polyainos IV 7,3). Sikyon was thus captured with ease. The garrison
withdrew to the acropolis, but surrendered shortly afterwards when Demetrios agreed
to let them return to Egypt (Diod. XX 102,2; Polyainos IV 7,3). He persuaded the
Sikyonians to move their main habitation from the harbor to their acropolis, where
they would be more secure against future enemies, and received divine honors for
liberating the city (Diod. XX 102,2–4; Plut. Dem. 25,2).

Demetrios's next target was Korinth, which in 303 was held by a garrison of
Kassandros under Prepelaos. There were elements in Korinth who were in sympathy
with Demetrios and promised to betray the city to him. Emboldened by his success at
Sikyon, Demetrios decided to employ the same tactics at Korinth and was again
successful: he set out for Korinth at night, sending one column of troops round to
attack from the direction of Lechaion (i.e., from the north) and himself marching up to
the south gate, where his friends let him into the city, the other citizens and the
garrison all being busy defending the Lechaion gate (Polyainos IV 7,8; Diod. XX 103,
1).
[16]
The garrison troops took refuge on two hills—Sisypheion and Akrokorinthos—
but when Demetrios rapidly took Sisypheion by storm, Prepelaos and his men on
Akrokorinthos were intimidated into surrendering on terms and returning to
Kassandros, leaving Demetrios in full control of Korinth and the Isthmos (Diod. XX
103,2–4).
[17]
These successes, gained with minimal losses in a few weeks of
February/March 303, made a deep impression on the Greeks: the Athenians, for
example, who had a contingent of soldiers serving with Demetrios, vowed annual
sacrifices to Athena Nike, Good Fortune, and the Saviours (i.e., Antigonos and
Demetrios) for the successes thus gained with few or no casualties among their
citizens serving with Demetrios.
[18]
The Korinthians, we are told, were garrisoned by Demetrios until the end of the
war at their own request (perhaps really at the request of the pro-Antigonid faction),
and Demetrios moved on to campaign in the Argolid, Achaia, and Arkadia. Inscriptions
attest to his capture
[16][17][18]

and liberation of Troizen and Epidauros, and towards the end of June he was in
control of Argos, where he presided at the festival of the Heraia (Plut. Dem. 25,1–
2).
[19]
While he was in Argos, Demetrios contracted his third marriage, to Deidameia
the sister of Pyrrhos of Epeiros, a marriage which offered him two advantages: since
Deidamia was a relative of Olympias and had been betrothed originally to Alexandros
IV, Demetrios gained a link to ancient royalty by marrying her; and as she was the
sister of the reigning king of Epeiros, Demetrios acquired a valuable ally against
Kassandros, for Kassandros was an enemy of Pyrrhos (Plut. Dem. 25,2; Pyrrhos 3,1–
4,2). Demetrios then went on to liberate the cities of Achaia and brought over to his
side all of Arkadia except Mantinea, apparently meeting serious resistance only at
Orchomenos. There the garrison installed by Polyperchon held out against him for a
while, but he eventually took the place by storm. Since no aid was forthcoming from
Kassandros or Polyperchon (who was apparently lying low in Messenia at this time),
[20]
this led the other forts and cities to go over to Demetrios without delay, including the
important city of Elis (Diod. XX 103,4–7; IG IV
2
. 1 68 V, lines 136–37). With the
northern and central Peloponnesos thus brought into the Antigonid camp by the end
of the autumn of 303, plans could be laid for the creation of the great league of Greek
cities that was to institutionalize Antigonid influence in Greece while enshrining
Antigonos's policy of making the Greek cities autonomous.
