“We should hold a party commemorating the Battle of New Orleans where British suffered the most lopsided of all defeats, ironically after the war was officially over.”
The Treaty of Ghent had been signed on Christmas Eve 1814, and ratified by Parliament on 30 December 1814. But it had no force until official word crossed the Atlantic and the treaty was ratified by the US Senate, which transpired on 18 February 1815. British forces under Gen Edward Pakenham attacked New Orleans on 8 January 1815; thus New Orleans became the final major land action.
The war at sea went on for many more months, as far-flung warships did not receive word for a long interval.
Crossed communications due to slow travel bedeviled that era; national leaders, diplomats, and military commanders of that era acknowledged the inherent problem and coped as they could. It is brainlessly anachronistic and condescending for moderns to sneer at them. Unseemly, also.
I recently read a book that described the War of 1812 as an American civil war.
Indeed I would go so far as to say the War of Independence was a civil war, not fought between Americans fighting to overthrow foreign “British” rule but between British Americans with different opinions about how to govern the place.
Revere didn’t shout “The British are coming!” as post-war revisionists made out because they all regarded themselves as British, but “The regulars are coming!” a different thing entirely posing the struggle not as a fight against foreign oppressors but between the forces of an over-bearing state and local volunteer militias, who were fighting for freedom from central government and their hired minions.
You can see why federally funded state employees in government-run schools find such an idea frightening and prefer to brainwash the children into believing the war was against foreigners.
