In the ordinary course of events Collingwood parted from his gallant relative, and sailed for some time with another officer. Between these two services thirteen years were consumed, and during that period he made the acquaintance of Nelson. At its termination he went to Boston with Admiral Graves, and was thus present at the battle of Bunker’s Hill, in command of a party of seamen to assist and supply the troops, who, under General Gage, encountered the insurgent colonists. After that event he was advanced to the rank of lieutenant; and in 1775 joining the “Hornet” sloop, in that capacity he sailed to the West Indies. The ship in which Nelson was lieutenant came to the same station; and with the immortal hero Collingwood renewed the feelings of friendship, which, cemented in the interval by many high aspirations and bright dreams, were strikingly and glowingly displayed on another and more glorious day. Meantime Collingwood had the good fortune to succeed his friend as commander of the “Badger,” and, subsequently, as a post-captain in the “Hinchenbroke” frigate, with which he was ordered to proceed to the Spanish Main, and employed on the expedition sent up the river San Juan. The climate to which he was now exposed was in the highest degree pestilential; the majority of his crew fell victims to its excessive insalubrity; and in this perilous situation he was sustained and saved from sharing their fate by a remarkably strong constitution. Right glad, however, with all his powers of endurance, must he have been when relieved in the autumn from this scene of woe and suffering. He was then appointed to the command of the “Pelican.” With that frigate, of twenty-four guns, he captured a French vessel, recovered from the enemy a richly-laden Glasgow merchantman, and was soon after wrecked among the rocks of the Morant Keys. He next obtained the command of the “Sampson,” a ship of sixty-four guns, which was paid off at the peace of 1783. Then he was dispatched, in the “Mediator,” to the West Indies, where he and his younger brother, a naval officer of great promise, who filled an untimely grave, actively aided Nelson in enforcing the provisions of the Navigation Act against the encroachments of the Americans.
