With the ending of the World War I, surviving sportsmen began to come back to Beşiktaş one by one. Şerey Bey, the founder of football section, also returned from the Romanian front. It was not easy to keep the club running during the occupation of Istanbul. The materials and documents of the club hidden in a nearby church were later taken to a building in Akaretler to prevent them from being plundered by the invading Greeks. While Beşiktaş were secretly engaged in the National Resistance efforts against the Allied Forces, Şeref Bey managed to rebuild the club’s football team.
