The Malay piratical proas are from six to eight tons burden, and run from six to eight fathoms in length. They carry from one to two small guns, with commonly four swivels or rantakas to each side, and a crew of from twenty to thirty men. When they engage, they put up a strong bulwark of thick plank; the Illanoon proas are much larger and more formidable, and commonly carry from four to six guns, and a proportionable number of swivels, and have not unfrequently a double bulwark covered with buffalo hides; their crews consist of from forty to eighty men. Both, of course, are provided with spears, krisses, and as many fire arms as they can procure. Their modes of attack are cautious and cowardly, for plunder and not fame is their object. They lie concealed under the land, until they find a fit object and opportunity. The time chosen is when a vessel runs aground, or is becalmed, in the interval between the land and sea breezes. A vessel underway is seldom or never attacked. Several of the marauders attack together, and station themselves under the bows and quarters of a ship when she has no longer steerage way, and is incapable of pointing her guns. The action continues often for several hours, doing very little mischief; but when the crew are exhausted with the defence, or have expended their ammunition, the pirates take this opportunity of boarding in a mass. This may suggest the best means of defence. A ship, when attacked during a calm, ought, perhaps, rather to stand on the defensive, and wait if possible the setting in of the sea breeze, than attempt any active operations, which would only fatigue the crew, and disable them from making the necessary defence when boarding is attempted. Boarding netting, pikes and pistols, appear to afford effectual security; and, indeed, we conceive that a vessel thus defended by resolute crews of Europeans or Americans stand but little danger from any open attack of pirates whatsoever; for their guns are so ill served, that neither the hull or the rigging of a vessel can receive much damage from them, however much protracted the contest. The pirates are upon the whole extremely impartial in the selection of their prey, making little choice between natives and strangers, giving always, however, a natural preference to the most timid, and the most easily overcome. When an expedition is undertaken by the Malay pirates, they range themselves under the banner of some piratical chief noted for his courage and conduct. The native prince of the place where it is prepared, supplies the adventurers with arms, ammunition and opium, and claims as his share of the plunder, the female captives, the cannon, and one third of all the rest of the booty.
