After losing the Battle of Harlem Heights on Manhattan, and the Battle of White Plains a short time later, he had to flee through New Jersey to protect Congress in Philadelphia.
From Wikipedia:
The failure of the Continental Army to hold New York also brought about a rise in Loyalist activity, as the city became a haven for refugee supporters of the Crown from elsewhere across the region. The British therefore actively recruited in New York and New Jersey to build regiments of provincial militia, with some success. Loyalists in these areas may have been motivated by seeing elements of the rebel army head home after their enlistments ended.
One New York Patriot militia leader wrote that thirty of his men, rather than reenlisting with him, had instead signed up with the enemy. (Sounds like some of the "Sunshine Patriot" Anne Coulter brigade Freepers we have today!)
On November 30 Admiral Howe offered amnesty to anyone that had taken up arms against the Crown, provided they swore an oath to it. Washington responded with his own proclamation suggesting that those who did not renounce such oaths should immediately go behind British lines.
As a result, New Jersey became a civil battlefield, with militia activity as well as spying and counterspying continuing for the rest of the war.
We just might need to split the country's population. The Left can go flee behind "British" lines (Canada).
“...The Left can go flee behind “British” lines (Canada)...”
That works for me....
