There can be no other explanation other than a roman defeat, that stopped them utilising the Eston hills and Tees inlet as a Roman strong hold ! There is no evidence of Rome gaining any type of a hold on the area we now know as Cleveland , to any military strategist this would point to only one thing a fear by the Romans to attempt to attack the area !
I have found no evidence of actual Roman occupation in the ancient area of Cleveland, there have been a few isolated villas found but these were of so called Romano British origin, again no evidence of any Roman occupation, ie the skills to build these villas would be readily available at the time of the partial occupation of Britain. everything in this area regarding the Romans points towards a Roman defeat or reluctance to tackle the occupiers in direct confrontation .
The boundary as I see it , i.e. the Romans appear
to have stopped here ! with this view of ancient
Cleveland in front of them !
Piercebridge Roman Fort - Wikipedia, the free encyclopedia This location is to the west of Cleveland , again to me this points to the Romans avoiding the area we now know as Cleveland , also there is no references I can find of Roman writings about the area .

A rising of the Brigantes has often been posited as the explanation for the disappearance of the Ninth Legion, stationed at York is it just coincidence that York lays just to the south of the Cleveland hills, and Tees basin, that was never conquered or wrote about by Rome ! ?
. According to the eminent 19th-century German classicist Theodor Mommsen, "under Hadrian there was a terrible catastrophe here, apparently an attack on the fortress of Eboracum [York] and the annihilation of the legion stationed there, the very same Ninth that had fought so unluckily in the Boudican revolt." He suggested that a revolt of the Brigantes soon after 108 was the most likely explanation.
The above all supports my theory that Rome never conquered the area we now know as Cleveland , and in all probability the area was a Briton strong hold !
