in like manner. The gates, the openings of which were 12 or 13 
feet wide, were approached from the exterior by drawbridges; but 
it is doubtful whether a trench completely surrounded the town. 
Entries in the Siege Accounts show, however, that in order to 
guard against chance possession by the enemy of the east bank of 
Sutton Pool a trench was made from the Friary Gate to the 
East Gate along the margin of the Pool, and filled with water. 
There are entries of payments to Mr. Thomas Crampporne for 
‘<sleauseing ye Trenches between Fryrey Gate & ye drawbridge.” 
The drawbridge can only be that at East Gate, and without such a 
trench there would have been nothing to prevent an enemy, 
embarked on Sutton Pool, landing on a perfectly open piece of 
ground within the walls. The gates were strongly defended. In 
August, 1645, one Matthew Stanley built a house over the sally- 
port at the Old Town drawbridge; and in January following 
Ludowick Stitson built a new guard-house at Frankfort. The 
chief magazine was in the Castle, but houses were hired for 
temporary magazines near the walls. Part of the Castle still 
remains at the bottom of Lambhay Strect. 
The outworks were of earth, and in their most complete form 
were stockaded. Most of them were of triangular outline. The 
cannon were mounted on wooden platforms, the provision of which 
formed no small item in the expenditure. Possibly an entry of 
payment for ‘‘threshells with ringes and swivells for the out- 
works” refers to something connected with these platforms. At 
the principal outposts there were horse guards. The breastwork 
was merely a low rampart and ditch. 
I now return to the history of the progress of the Siege. 
The next attack was made about the middle of August by Col. 
Digby, who with 600 horse and 300 foot formed his head-quarters 
at Plymstock, and for five or six weeks so scoured the country that 
no provisions could be brought in. But the chief troubles of the 
town just then were internal. Sir Alexander Carew, commander 
of the fort and island, was discovered in communication with the 
King’s army. Clarendon* says he was in treaty with Sir John 
Berkeley; Rushworth, that he held intelligence with Col. Edgeumbe . 
and Major Scawen by night.t| Mayor Francis, however, was a 
man of decision; and the treachery of a servant supplying all the 
evidence required, Sir Alexander was apprehended and sent to
