Stragetical advice: when antonious finish up sieging Erdek and put it in his control the best way to defend it is to make a canal on the strip of land connecting it to Anatolia build 1 bridge overwatched by 2 fortresses fielding cannons to artificially create a choke point so that Antonius's men can defend Erdek even with less men even better if Antonious has field artillery with grapeshots can be very devastating to enemy forces in choke points. second once Antonious is done in the sea of marmamara he should expand his fleet and think about taking control of all the islands in the agean sea so that any trade ships passing through the agean and maramara can be taxed increasing Antonius's financial power. after that start the conquest of greece while everyone is busy with the ottomans and secure Antonius's position in the balkans with a large navy to boot.
