However, in the sense that it shows the Mexicans suffering significant casualties, it is more or less accurate.

Of course, on the other side of it, US Army attacks against Mexican forts/fortified cities, conducted about a decade later, generally carried their objectives with much more favorible casualty ratios while attacking in daylight.
In terms of forts in game, it does not really matter how you deploy them (in terms of facing, etc.) Just put the soldiers at a section of wall, and they will man it the best the can.
