This achievement can be hard to earn but there are different ways to complete it. You also will get the trophy on your main civilization. First of all there are a couple requirements for my strategy. You need a powerful navy, especially the 'normal' attack and 'siege' boat. Also you need strong palintons or a different siege units.
Take four standard enemies, with a heroes of your choice. Do not take General Batoshipip as your enemy. If you do, you will be destroyed before you know it. [EDIT: You might want to fight against the celts, because their navy isn't that good] For the map take the small duelling island, with much resources. Set the victory condition on standard.
When you start make sure that you are on the lowest island. The enemies will be on a single island at the top. Make a couple of villagers and put them on wood and food. Make two docks as soon as possible and start making houses. Meanwhile also put villagers on gold. Start making as much 'attack' boats as you need and try to destroy your enemies docks. When they haven't any docks left, try to surround your enemies island to make sure they can't make a new one again. If you can't surround the complete island in time. just make sure that their transport can't make it to your little island.
When your enemies island is surrounded just start ageing up. You can also work on the defence of your island with towers, but that isn't needed . When you reach age four start training 'siege' boats and send them to different spots close to your enemy island. Now it is time to start snuffing them out. Try to destroy and kill their units but watch out that your ship's aren't too close to their shore or they can destroy them.
When your enemies are weak enough and/or are running out of resources start making a fortress and some transport ships. When those are complete make some 'siege' units and put them in your transport ship. Send that ship as close to as possible to a town centre and destroy it there. Do this four time and the victory is yours!
It is possible to lose with this strategy, if you make an mistake or if your enemies break through your navy. Then they can rush your island with a lots of troops. Just don't lose the sea and always keep an eye on there shore. If you wondered, I didn't make a single infantry unit or barrack. Just completely focus on the navy.
More solutions, tips or comments are welcome. If needed, I will edit my solution.
Good luck!
