W. D. Bernard, Narrative of the Voyages and Services of the Nemesis from 1840 to 1843
“ Many of the Chinese officers boldly and nobly met their death, some even courted it; they dreaded their master's wrath and their own degradation more than the loss of life at the hands of their country's foe. Among these, the most distinguished and most lamented, was poor old Admiral Kwan, whose death excited much sympathy throughout the force; he fell by a bayonet wound in his breast, as he was meeting his enemy at the gate of Anunghoy, yielding up his brave spirit willingly to a soldier's death, when his life could only be preserved with the certainty of degradation. ”
