FJ Vs. Polish Assault Rafts

[SGTGunn]

Hi,

I'm playing a long campaign with Germany. My core force is a company of Fallschirmjägers. My first battle is a meeting engagement against Poland. I chose a pre-made map (the Rozan Map) which has a small river dividing the map in half. The victory hexes were located in the center of the map in a town (Rozan) just on my side of the river. A bridge crosses the river (from the polish side) into the town. My troops jumped into drop zones just west of the town, and advanced to the objectives on foot. Reaching the edge of the river, they have discovered large numbers of Polish Assault Rafts, apparently "beached" one hex inland from the river, on the western bank (my side), but no Polish troops were anywhere near the rafts.
The poles made a limited attempt at crossing the bridge (with some cavalry), but otherwise seem content to mass up on the far bank and do little else. The bridge is intact. 1st question - what's up with the rafts? They just lay on the bank, let me shoot them up, and occasionally fire back with pistols. Question two - the Poles seem reluctant or unable to cross the river. Is this a limitation of the Computer AI? Or is there a problem because the mission is a meeting engagement, rather than a river crossing?

Thanks,

Adrian
