The Thirty Years War [Concluded]

[Beskar]

You could build a seige cannon, that would nulify the effect. or build a boat for transport then send your units out to sea.

If that is not possible, I would do temporary military access, with your units effectively being disarmed by dutch forces, then you are allowed to pick your weapons up when you leave. (aka, military access claus which makes you unable to use your units against me) Though, Ibn would have to say whether or not that is possible.

If worse comes for the worse, you could disband and I will pay the cost of you replacing your units. However, I am guessing that would require turns for you to replace, which you don't have at this moment.
