this position he remained from October 1808, to January 1810, and during that period he was present at the memorable Battle of Corunna. Leaving Semiramis he went on board the 74-gun Norge as master's mate; and being again stationed off the coast of Portugal he was present at the Siege of Cádiz by the French under Marshal Soult, and took part in the attack on St. Mary's, where he was in command of a rocket boat, and narrowly escaped death through the boat being sunk by a round shot, and those who were not killed left struggling in the water until a rescue could be effected. Johnston and another officer were subsequently placed with a crew of 150 men on board the captured French 80-gun ship Neptune — one of the vessels that escaped from Nelson's fleet after the Battle of Trafalgar — and ordered to proceed with her to Majorca, where she was to be laid up; and this service having been accomplished, he returned to Norge, which shortly afterwards sailed to England for the purpose of joining the Scheldt fleet under the command of Admiral Sir William Young.

At this period Great Britain was at war with the United States, and the Asia sailed for Bermuda, where Johnston received his commission as lieutenant, and was appointed to the command of an advice vessel, or what at the present day would be called a despatch boat. In this little vessel he saw some fighting, and was present when a British fleet ascended Chesapeake Bay and captured the city of Washington. Rejoining Sir Alexander Cochrane, on board Asia, at Port Royal, Jamaica, Lieutenant Johnston was directed to place himself under the orders of Sir Peter Parker, Bart., commanding the frigate Menelaus, then engaged in blockading the approaches to the city of Baltimore. This he did, and he was present with Sir Peter Parker in the night attack on Moorefields, where Sir Peter Parker was killed. The death of his commander caused Lieutenant Johnson to be sent with despatches announcing the event to Admiral Cochrane, and then returning to Menelaus. He remained on board that vessel until after the unsuccessful attack by the British forces on Baltimore, when he was directed to proceed to Jamaica, and again place himself under the
