After returning from Virginia he was sent on an expedition against New London where he first breathed the vital air. He landed his troops in two detachments--one on each side of the harbor. He led one against Fort Trumbull which could make but a feeble resistance. Fort Griswold made a spirited defence against the other division commanded by Lieut. Col. Eyre but was compelled to yield to an overwhelming force. When the Americans surrendered but seven men had been killed within the lines--after the surrender a murderous slaughter was commenced by the British and about 100 killed and wounded. On entering the fort an English officer inquired who commanded the garrison. Col. Ledyard presented his sword and answered--"_I_ did--but _you_ do now." His sword was taken by the officer and immediately plunged through his heart. In the attack the enemy had 48 killed and 145 wounded. Arnold commenced his favorite work of plunder--loaded and sent away 15 vessels mostly freighted with private property--fired the place and reduced 60 dwelling-houses and 84 stores to ashes and in his haste four of his own ships were burned. He completed this work of destruction and was absent from New York only eight days. Such expeditions afforded the richest aliment for the black heart of this traitor. He continued the scavenger of the British army to the close of the war and then removed to London where he died in 1801. To the lasting disgrace of the British government Arnold received a liberal pension to the time of his death which is continued to his descendants and is frequently complained of by the British press. With the blackness of eternal disgrace resting upon his character this traitor has had apologists among American writers. They attribute his treason to a want of liberality on the part of our government. I have said the want of means to give full scope to his sordid passions was the cause. A want of liberality does not appear upon the record. He was allowed more than justice demanded--more than other officers under like circumstances. He was unsound at the core--void of moral rectitude--was proved dishonest before the commissioners of accounts--the committee of Congress and the court-martial. His name should _then_ have been erased from the roll of officers regardless of consequences. That would have saved him from the treason he perpetrated--the accomplished Andre from the scaffold and thousands from the ravages subsequently committed by the reckless traitor. All apologies for Arnold are sophisms. His name is stamped with a lasting infamy that blots out the noble deeds that preceded his Lucifer-fall. JOSHUA BARNEY.
