ROMANO-BRITISH SUFFOLK There might also be a look-out and signalling station at Caister, north of Yarmouth, where Roman remains have been found. From it there would be a wide view both over the North Sea and the passage into Breydon. Nor must we forget the fleet. To be of any service there must have been a certain number of vessels for the defence of the coast and harbours near each station, and Breydon offered a good anchorage for Gariannonum. From he Notitia Dignitatum, compiled it is believed in the 5th century, it appe? s that the fortress was garrisoned by a body of cavalry, the Stablesian Horse. The land for many miles south of the station was flat and in placts high above the sea, and well adapted for any work cavalry would have to do ; ani from this point on the Waveney as far as Dunwich a Roman port, presumably walled, could be easily patrolled when necessity arose.^" Walton. — Travelling southward, at the south corner of the county and upon its coast line (plan III) will be found the compa- nion fortress to the one just described. But before giving any account of what is known of it the district which it was erected to guard must be no- ticed, or the reason for the need of its existence will not be apparent. At this south- ern corner of Suf- folk there are three waterways, two of which penetrate far into the land. The first and most east- erly, the Deben, so called from the little stream which flows into it, runs up as far as Wood- bridge, and a short distance beyond this town is Burgh, already mentioned. Farther south come the estuaries of the Orwell and the COAST LINE OF SUFFOLK AND ESSEX FROM BAWDSEY HAVEN TO WALTON ON THE NAZE Xbc DOrreo DNt shows tiiaH watzr mark.
