Why did the acadians surrender to the British?

It is most accurate to say that the American War for Independence ended not in a surrender by the British but, rather, with a British acknowledgement of defeat. After eight long years of hostilities, the British were war-weary and otherwise exhausted with the effort. Further, their military was also over-stretched due to its many other commitments around the globe -- and could not achieve its aim of subduing the American rebellion.
