The English now conceived that their secret was undiscovered, and that their sufferings would forthwith be mitigated by the supply drawn by their lines. They commenced briskly and successfully; but, alas! their success was of short duration. Sanders' secret became known to the Scots army. The night-watchers had often seen the old man's boat leaning on the shore at that point at all hours of the night; for he was always free to go about plodding for fish when he pleased. His cry was heard at that spot, and the boat was now missing: the place was watched, and in two days the Englishmen's secret, on which they so much relied, was discovered, and quite cut off; and that powerful garrison was now left with absolute famine staring them in the face. As in all cases of utter privation, the men grew ungovernable. Their passions were chafed, and foamed like the ocean before the commencement of a tempest, foreboding nothing but anarchy and commotion. Parties were formed of the most desperate opposition to one another, and every one grew suspicious of his neighbour. Amid all this tempest of passion a mutiny broke out:--a strong party set themselves to deliver up the fortress to the Scots. But through such a medley of jarring opinions what project could succeed? The plot was soon discovered, the ring-leaders secured, and Sir Stephen Vernon, Musgrave's most tried and intimate friend, found to be at the head of it. No pen can do justice to the astonishment manifested by Musgrave when the treachery of his dear friend was fully proven. His whole frame and mind received a shock as by electricity, and he gazed around him in moody madness, as not knowing whom to trust, and as if he deemed those around him were going to be his assassins. "Wretch that I am!" cried he, "What is there more to afflict and rend this heart? Do I breathe the same air? Do I live among the same men? Do I partake of the same nature and feelings as I was wont? My own friend and brother Vernon, has he indeed lifted up his hand against me, and become one with my enemies? Whom now shall I trust? Must my dearest hopes--my honour, and the honour of my country, be sacrificed to disaffection and treachery? Oh Vernon--my brother Vernon, how art thou fallen!"
