Problems with PRussian Conquest

[Kaurne]

I need some help. I am playing the Short campaign as Prussia, and it is currently 1729. I have conquered all of the required regions for victory apart from Denmark, which is currently possesed by Sweden. Despite there being a little arrow from the mainland of denmark to the island which Copenhagen is on, I cant get over there. There is a Swedish fleet in the region, which might be the cause, but I dont know. The Swedish fleet is much stronger than mine, as I only have galleys (I built lots of commercial ports in an attempt to get trade going). I have 40 turns to conquer Denmark, but I have no idea how to do it. Please help.

Note: I have ~5k with an income of ~10k a turn. Thanks!

Work on building up your navy. With 40 turns you have plenty of time to build a bunch of brigs to compliment your galleys. If you are going to go to war with Sweden and you focused on trade ports, you are going to need a navy to protect your trade lanes.

another strategy would be to get a peace treaty then get ur men on any ship land at coppenhagen, declares war automatically, take it and enjoy.. this takes from 1 to 3 turns so no worries for the next 30 something.

Ask for 5 turns military access in return for indefinate access or some money. Then roll some blokes over there and Robert's your fathers brother.
