He served with distinction in Flanders, and at the end of the Seven Years' War he was chosen to command the companies selected for service in Portugal. When so employed, he won the respect of all by his dignified firmness and courtesy, and laid the foundation of an affection towards himself from the officers serving under him which never even waned. On his staff in Portugal was a subaltern bearing a name honoured then as now in the Artillery,—Adye. Lieutenant S. P. Adye was afterwards, as a Captain-Lieutenant, aide-de-camp to General Pattison when in command of the Royal Artillery in New York, and was a most able and energetic staff officer. In 1769 Colonel Pattison was sent to Venice to superintend the organization of the Venetian Artillery. From private letters, which are still in existence, it would appear that he had a very difficult task, not so much with the Artillerymen as with the authorities, who were disposed to break faith with him. But as he simply threatened to resign if they did not keep their promises, he obtained what he wanted; and it may be said of James Pattison that he never wanted more than justice. General Pattison, as has already been mentioned, succeeded Colonel Cleaveland in the command of the Fourth Battalion of the Royal Artillery in America. He succeeded one who was a soldier, but no statesman,—who conceived that the utmost expected of him was to despise and defeat any enemy who might be opposed to him. General Pattison was equally sensible of his duty as far as military operations were concerned; but he went beyond his predecessor in the liberal and statesmanlike views he took of the state of America. In his official reports, it is needless to say, he did not enter into details beyond his province; but his private correspondence is a mine of wealth to the student of the great American War, and it has been placed at the disposal of the compiler of this work by the representatives of the family. The following letter is a dispassionate and valuable contribution to the history of those stirring times, and reveals at once the able character of the writer and the state of the American Colonies. In writing to his brother from Philadelphia, in December, 1777, he says:
