A fortnight later the fourth and last instalment arrived at Killala Bay; but the Admiral, hearing that the rebellion was over, promptly weighed anchor and returned to France. Thus ingloriously ended the French attempts at the invasion of Ireland. The calling-in of the foreigner had been of as little use to the cause of Irish rebellion as it had been two centuries before. By the end of the year the worst of the rebellion was over. But the evil it had wrought was incalculable. How many had perished during that terrible summer will never be known; the numbers have been variously computed at from 15,000 to 70,000. At the outset of the rebellion--in February 1798--Lord Clare had made a memorable speech in the House of Lords, which has been so often misquoted that it is well here to cite the passage in full:-- "If conciliation be a pledge of national tranquillity and contentment; if it be a spell to allay popular ferment; there is not a nation in Europe in which it has had so fair a trial as in the Kingdom of Ireland. For a period of nearly twenty years a liberal and unvaried system of concession and conciliation has been pursued and acted on by the British Government. Concession and conciliation have produced only a fresh stock of grievances; other discontents of Ireland have kept pace with her prosperity; for I am bold to say there is not a nation on the habitable globe which has advanced in cultivation and commerce, in agriculture and in manufactures with the same rapidity in the same period. Her progress is now retarded, and it is a heart-breaking spectacle to every man who loves the country to see it arrested only by the perverse and factious folly of the people, stimulated and encouraged by disappointed statesmen."
