"It happens that it is not a disguise at all this time. I am what I seem to be, a naval lieutenant. I have been serving in the navy ever since I joined it, ten days after I sailed from here, and was through the siege of Acre with Sir Sidney Smith. As you see, I have had the good fortune to be promoted. I have been serving ashore since we first landed here, and have been up to Cairo with the force that marched there as a sort of guide and interpreter."
