But meanwhile William of Orange had received his invitation to come with an armed force for the delivery of England from the Stuarts, and for some months had been making preparations for an invasion. It was long before James awoke to his danger, but when at last he perceived it he hastened to strengthen the Army. Commissions were issued for the raising of new regiments, of which two are still with us as the Sixteenth and Seventeenth of the Line, and of new companies for existing regiments. Four thousand men in all were added to the English establishment; three thousand were summoned from Ireland, and as many more from Scotland; and James reckoned that he could meet the invader with forty thousand men. On the 2nd of November William, after one failure, got his expedition safely to sea, and by a feint movement induced James to send several regiments northward to meet a disembarkation in Yorkshire. These regiments were hastily recalled on the intelligence that the armament had passed the Straits of Dover steering westward, and fresh orders were given for concentration at Salisbury. In a short time twenty-four thousand men were assembled at the new rendezvous, but before James could join them, he received news that Lord Cornbury, the heir of his kinsmen the Hydes, had deserted to the enemy. Cornbury had attempted to take his own regiment, the Royal Dragoons, and two regiments of horse with him; but officers and men became suspicious, and with the exception of a few who fell into the hands of William's horse and took service in his army, all returned to Salisbury. Before setting out for the camp James summoned his principal officers to him--Churchill, since 1683 Lord Churchill, and recently promoted lieutenant-general; Henry, Duke of Grafton, colonel of the First Guards; Kirke and Trelawny, colonels of the Tangier Regiments. One and all swore to be faithful to him; and the King left London for Salisbury.
