Passage: Philetaerus served Lysimachus until 282 BC, when perhaps because of conflicts involving the court intrigues of Arsinoë, Lysimachus' third wife, Philetaerus deserted Lysimachus, offering himself and the important fortress of Pergamon, along with its treasury to Seleucus, who subsequently defeated and killed Lysimachus at the Battle of Corupedium in 281 BC. Seleucus himself was killed by Ptolemy Ceraunus, a brother of Arsinoë at Lysimachia a few months later.Though nominally under Seleucid control, Philetaerus, especially after the death of Seleucus, had considerable autonomy and was able with the help of his considerable wealth to increase his power and influence beyond Pergamon. There are numerous records of Philetaerus as benefactor to neighboring cities and temples, including the temples at Delphi and Delos. He also contributed troops, money and food to the city of Cyzicus for defense against the invading Gauls. As a result, Philetaerus gained prestige and goodwill for himself and his family.During his nearly forty year rule, he constructed the temple of Demeter on the acropolis of Pergamon, and the temple of Athena (Pergamon's patron deity), and Pergamon's first palace, and he added considerably to the city's fortifications.Philetaerus was a eunuch, though scholars differ on the reason for his castration.  Attalus I, the first Attalid king of Pergamon, explained that when Philetaerus was a baby, he was brought into a crowd where he was pressed upon and his testicles were crushed.

Question: What did he give to the troops to assist in protecting the the city of Cyzicus?
money and food
