Napoleonic Title by JTS with smaller map scenarios?

[Sean]

Finally bought Eckmuhl in the lastest WDS Sale.
Thanks for the suggestion, it seems like it what I was looking for.

Played the first scenario and now playing the 2nd scenario 01a at the moment.
Called something like 'Delay at Landshut ',game is on my other laptop.
There is 2 bridges that I as the Austrian player need to cross initially.
My infantry all crossed the 2 Bridges without hiccup,had to dispatch a few French first on the way through.

However I cannot seem to get my Artllery ,Cavalry or Supply wagons over the 1st Bridge.
Is this a scenario setting or is it a bug or am I not doing something correctly?

Can someone that has played the 2nd scenario comment as to whether non infantry can cross the Bridge I allude to?
