The city of Manila, according to the map of Father Murillo, is located in 14° 40' of north latitude, and 158° 35' east longitude, on a tongue of land which terminates in a point, and forming the figure of a jug or flagon, whose extremity or neck is formed by the above point itself and contains the royal fort of Santiago. At the west it is terminated by a large bay at the north by the Pasig River, which bathes its walls. On the land side from south to east, it is defended by four flat bastions with their casemates, and right flanks covered with orillons, and with ditches, covered way, and glacis. Along the sea, the city is fortified by a long curtain with five little flat bastions, a reduct located at a great distance from the wall. The lines of defense have such disproportion from one another, that those bastions cannot be defended reciprocally. It is impossible, further, to prevent the approach by the curtain, because there is neither ditch nor terreplein. Then too, the parapets are only one foot wide, and the curtain six. The curtain embracing the north side, bathed by the river, and which has a kind of curvature where it forms two reëntrant angles, is in the same condition of weakness as that of the sea, and is defended by two small bastions, which present the same defect noted above in their lines of defense. From the bastion of San Gabriel to the gate of the Parián on the east of the city, is located a false screen or barbacan with its parapet and banquette. It is defective, for it is fallen, and has no gate for the retreat of the soldiers. The gate of the Parián is covered and defended by a small outer work in the form of a crown, and the royal gate by a ravelin so poorly placed and so poorly ordered, that it cannot defend the faces of the collateral bastions of San Andrés and of the foundry. The flanks of the two latter bastions are not any more capable of defending the faces of the ravelin. It must be added to the above that all those fortifications are very old and defective: the walls; the chemise, or revetement, three feet thick at the cordon, without counterfort; the escarp and counter-escarp fallen in part; and almost everything useless. The covered way is very short and filled with thickets and bushes. Its parapet is in ruins and it has no stockade or palisade. It is so low, that it leaves the most essential parts of the bastions and curtains open clear to the foot. The embrasures are poorly placed. The gates on the sea side, are pierced through, and so old and so used up, that they cannot offer any resistance at all. The esplanades of the boulevards are so irregular and so rough, that it is impossible to maneuver with the artillery, which, besides, was mounted on ship's carriages so old that they could not be fired without danger of being dismounted.
