In the absence of Demetrius, Cassander now felt able to send further reinforcements to Lysimachus, under the command of his brother, Pleistarchus. Since Demetrius was guarding the easy crossing points at the Hellespont and the Bosphorus, Pleistarchus attempted to ship his men directly across the Black Sea to Heraclea, using the port of Odessos. The men had to be sent in batches due to a lack of ships, and although the first batch arrived safely, the second shipment was intercepted by Demetrius's fleet, and the third wrecked in a storm. Pleistarchus himself narrowly survived the wreck of his command ship, eventually being carried to Heraclea to recuperate over the winter. Similarly, the concentration of Antigonid forces in Asia now made Ptolemy feel secure enough to bring an army out of Egypt to try to conquer Coele Syria. He captured a number of cities, but while laying siege to Sidon, he was brought false reports of an Antigonid victory, and told that Antigonus was marching south into Syria. He thus garrisoned the cities he had captured, and retreated into Egypt. At around the same time, Seleucus appears to have finished his march from the east, arriving in Cappadocia with his army, which he then sent into winter quarters.
