If you go to Google earth and pull up Wallsend fort, this is 4.5 acres so half of this is just over two. Then you have to loose 25% of that so to get a Cohort into an area of that size would be impossible, besides which the fort at the Pons Aelius was only there to gaurd the bridge no need to have a full Cohort unless we assume yet another fort on the other side of the river took the other half of the garrison.
