Bridges-WTF???

To have bridge battles IIRC your army must be position on the bridge on the map just like what Krusader said.

It is good to have range units when defending a bridge. Once had a Germania army of 8 Spear Warband and 4 Infantry attack my army of 14 Roman units. No doubt the ratio were in my favour there's no telling what might happen when fighting those dreaded Spearmen. My range units manage to route one of their spearmen while crossing and reduce another half in numbers.

When the acutally melee came, it wasn't too difficult. Killing the General helps alot I guess. IMHO bridge battles are the most fun.

One tip - never try to defend a bridge with hopelites. Everyone knows how they move right, and everyone knows that units that fall off the bridge die. Put 2 and 2 together, don't risk it, although it can work if you have a lot of archers.

i've won 50 battles on the same bridge with every time the same tactics
and i butchered them every time and the a=end i had 4 9 chevron foresters and 8 5 chevron chosen swordsmen and a 35 year old general every general that stood on that bridge became faction leader weird and loads of cavalry

It does get annoying with A.I. worthlessy using there troops to assault a bridge/crossing. Hopefully in the patch the A.I. will lay siege to the battlefield. Basically walk up to the bridge and park there instead of assaulting it. So you can either leave your army there, fight through or back off to get the comp to attack you.
