The Castle of Danda is scituated in the sea upon a little hommock, distant from the shoare a little more than a muskett shot; by nature very strong; wherein are at least 400 men, six great peeces of ordinance, and some 16 or 18 falconet and ravenet; envyroned with a wall, of 18 or 20 foote towards the land and some 14 foote towards the sea, round about, with battlements and half moones; and upon the top and middle of it a great house, and by it a block house, from whence we sawe three peeces of ordinance shott over to the S. side unto two Mallabarr friggitts which were coming into the baye (Foster, 1909, pp. 252-253; see also Banaji, 1932, p. 3).
