The tragical death of Sir Danvers Osborn by suicide two days afterwards, occasioned the elevation of Mr. de Lancey to the Gubernatorial chair, which he occupied till the 2d of September, 1755, when the new Governor, Admiral Sir Charles Hardy arrived, who administered the goverment till the 2d of July, 1757. Preferring a naval command Hardy resigned, and sailed in the expedition to Louisburgh, and Mr. De Lancey again took the reins of Government.
The ministry of England wished to keep the command of New York in the hands of Mr. de Lancey but it was then, as it is to this day, a rule of the English Government never to appoint a native colonist to the supreme command over his own colony. To effect their object in this case without violating their rule, they decided not to appoint any new Governor as long as Mr. de Lancey lived ; he therefore remained the Governor of New York until his death, some three years afterwards, on the 30th of July, 1760."
