Justus II, I thought about that, but wanted to force the Oda to have to attack at two places at the same time, so my ships remain loaded with the initial invasion force and are not able to move to complete the ocean railway (OR). My other thought was to get an ROP with Oda, to allow the initial troops to unload and the ships to move to complete the end of the OR, but that would be a dastardly way to begin a war. My other thought was to gift techs to Steam Power & coal (if they needed it) to the Oda so they could rail the connections for me, but that was going to consume too many turns to work. Under normal circumstances, a long war in Monarchy is not very painful, so I would take my time a protect lose as few units as possible in taking the Oda, so that the survivors would be ready for the invasion of the other continent. But in these conditions, where there were no future campaigns, wounded units were used to attain the goal ASAP.
