The incident Porcher depicts was reported in the Nautical Magazine and Naval Chronicle for 1852 (222-223). Porcher and the crew of the Cleopatra, Pluto and Semiramis were traveling up the Tunku river in pursuit of the Illanun [Iranun] pirates responsible for the murder of the HMS Dolphin's crew (see "25. Official visit of the Boats of the Cleopatra to the Pangeran Madoud's house"). When they arrived at the residence of Rajah Muda, marines and armed men landed to find white flags hoisted on the roof of the houses. Porcher reports: "In retaliation for their having fired at us the day before, when white flags were flying, both at the Chief's house, and also in our boats, about 40 houses were burned, and the little property that was found in them destroyed, as well as their paddy, fruit trees, etc." (34). The pirates returned fire again, killing one man and wounding two others. Porcher continues with a detailed description of the Iranun pirates from Mindanao, who were known for murdering crews of vessels "except those they are able to sell as slaves". The entire landscape is frenetic with action; figures are hiding behind foliage with guns, while gunfire issues from the British vessels in the river.
