Yes, the Brits moved south in part because of lack of meaningful success in the northern colonies.
Keep bumping this thread; the more people who see this nonsense, the better.

The Brits moved south because they had most of the North wrapped up.
Trivia time: When General Washington moved south to engage Cornwallis on the Virginia peninsula in a campaign that culminated at Yorktown, he needed to move through northern Virginia very quickly despite its nearly-impenetrable woods and terrain. He called upon his decades-old friend and fellow Burgess from Prince William County, Henry Lee II of Leesylvania, who was the father of Washington's favorite dragoon (cavalry) officer, "Light-Horse Harry" Lee, and therefore, the grandfather of General Robert E. Lee. Henry Lee, Colonel of the Prince William County militia, cleared the way by building a courduroy road through the woods (note to WhiskeyPapa and Ditto: the labor was done by white militia members, not slave labor). The roadway is still in existence and known to northern Virginians today as Telegraph Road.
