We find Don Blas in a very prepared posture.

Don Blas has been doing his best, this twelvemonth past; plugging up that Boca-Chica (LITTLE MOUTH) Ingate, with batteries, booms, great ships; and has castles not a few thereabouts and in the Interior Lake or Harbor; all which he has put in tolerable defence, so far as can be judged: not an inactive, if an insolent Don.

We spend the next five days in considering and surveying these Performances of his: What is to be done with them; how, in the first place, we may force Boca-Chica; and get in upon his Interior Castles and him.

After consideration, and plan fixed: "Monday, 20th March, Sir Chaloner, with broadsides, sweeps away some small defences which lie to left of Boca-Chica [to our LEFT, to Boca-Chica's RIGHT, if anybody cares to be particular].

Whereupon the Troops land, some of them that same evening; and, within the next two days, are all ashore, implements, Negroes and the rest; building batteries, felling wood; intent to capture Boca-Chica Castle, and demolish the War-Ships, Booms, and fry of Fascine and other Batteries; and thereby to get in upon Don Blas, and have a stroke at his Interior Castles and Carthagena itself.
