The Ist of October 1780 was a day of some importance because it was 
then that the Mill battery was begun by the Spaniards on the Neutral 
Ground, a battery that afterwards caused a good deal of annoyance to 
me ereisen: and was destroyed in the sortie of the 27th November, 
1781, 
There were at one time two Towers on the isthmus, the Devil’s 
Tower which still exists, and the Mill Tower near the Western beach 
1100 yards distant from the Grand Battery and destroyed by fire from 
the Rock during the Siege. Captain Spilsbury marks this tower in a 
sketch of these advanced works, which is inserted at this point in the 
Diary, and it was doubtless from it that the Mill Battery was named.
