You have not forgotten the wonderful cruise of Captain David Porter in the _Essex_, when he entered the Pacific Ocean and caused such havoc among the British shipping. He was appointed commander of the West India forces and arrived off Porto Rico in March, 1823. He was provided, in addition to his warships, with a number of barges, furnished with twenty oars apiece, and which were indispensable in following the pirates up the shallow creeks and into the shoal waters where the vessels could not go. [Illustration: OUR FLEET IN THE BALTIC.] Captain Porter was discreet but impatient with injustice. When one of his schooners was fired into by the Porto Rican authorities he promptly demanded an explanation, which was given. The most important incident of his service occurred in the autumn of 1824 and is known as the "Foxardo Affair." In October of that year the storehouse of the American consul at St. Thomas was broken into and robbed of much valuable property which there was reason to believe had been carried to the small port at the eastern end of Porto Rico known as Foxardo. Lieutenant Platt, of the _Beagle_, anchored off the town and asked the help of the authorities in capturing the criminals and recovering the property. The officer was treated with the grossest discourtesy. Having landed in civilian clothes, the authorities accused him of being an impostor and ordered him to show his commission. The Lieutenant produced it, whereupon they declared it a forgery and arrested him on the charge of being a pirate. After he and a midshipman who accompanied him had been insulted repeatedly they were allowed to leave. When Captain Porter learned of this outrage he entered the harbor with several of his vessels and sent a letter to the alcalde or governor, notifying him that he had one hour in which to send an explanation of his action. While waiting for the return of the flag of truce Captain Porter saw one of the shore batteries getting ready to fire upon him. Instantly, he sent a detachment, which captured the battery and spiked the guns. Then Captain Porter landed, and, after spiking another battery, made his way to the town. By and by the alcalde and captain of the port appeared and made such profuse and humble apologies that the officer could not refuse to accept them, and returned to his ship.
