@Kalopin,
At Detroit in 1812, Brock's force was decidedly inferior to Hull's force. Hull lost his nerve and surrendered to an inferior force. The number of Americans captured was almost twice the size of the force to which Hull surrendered. Brock then had to rush east to confront the American invasion. He foolishly lead an attack uphill at Queenston, and was killed for his trouble. That battle was won by the British, but only because of the attack of the Mohawk contingent, and after most of the New York militia had already retreated over the Niagara River. Subsequently, American forces invaded and occupied the Niagara peninsula, and the British were never able to dislodge them.
Back in the west, William Henry Harrison marched into northwest Ohio, constructed a fort, and successfully fought off two sieges. Tecumseh's Shawnees suffered heavy casualties, and Harrison drove off the British and retook Detroit. He then crossed the Detroit River and drove east, finally meeting and defeating the British and their Indian allies at the Battle of the Thames near the site of the modern-day London, Ontario. That was seen as the most decisive battle of the war after the battle of New Orleans. At the battle of the Thames, the British had 800 regulars and 500 Indians. Harrison's Americans out numbered them by almost three to one. That was where Tecumseh was killed. To repeat, the British were too weak a reed for the Indians to rely on their support to drive out the Americans.
At the high point of the wars with Napoleon, the British army only numbered somewhat over 200,000 men. The largest single contingent were the troops in the Iberian peninsula under Wellington. It was precisely because their army was so heavily involved in Spain that they had insufficient troops to send to North America. The British were driven out of western Upper Ontario, and never returned after the battle of the Thames. For all practical purposes, the Indians were f*cked in relying on British support.
The troops released after Napoleon's first surrender in the spring of 1814 were the ones who burned Washington. They didn't retreat because of any bullshit weather events that you're making up, they retreated because they were too small in number and didn't have the logistical support necessary to sustain a large force on land in Maryland and Virginia. There were only 4000 red coats, and probably fewer, at Bladensburg, the battle known as the greatest disgrace to American arms in our history. The British suffered far higher casualties than did the Americans, and many of those were from heat exhaustion. Yes, they burned Washington, and then they had to retreat to Cochrane's fleet, because they didn't have the supplies to sustain their troops, and they would soon be outnumbered as more and more American regulars were rushed to Maryland.
Most of Wellington's troops who had been shipped across the Atlantic were sent to Canada to try to stem the threat of the continued American occupation of the Niagara peninsula. They managed to force a stalemate, but they were unable to drive the Americans out--and they were the best that the British had to offer.
At New Orleans, Jackson had fewer than 5000 men at his disposal, and the Kentucky Militia on the west bank of the river ran away. Nevertheless, Jackson handed the red coats (of whom there were more than 10,000) a decisive defeat, including the death of Packenham, the commander. Total British casualties equaled nearly a quarter of their force, and more British troops were killed than the entire tally of American killed, wounded and missing.
In short, you don't know a goddamned thing about the history, so you just make up some bullshit about cometary effects. That was quite an active comet, allegedly causing an earthquake in 1811, allegedly causing Napoleon's defeat in 1812, allegedly responsible for the British retreat from Washington in 1814, and allegedly responsible for Jackson's victory at New Orleans in 1815. Funny how no reputable scientists seem to know about the comet that just wouldn't leave. You continue to fail to address how this comet was supposed to have affected events for more than three and years.
The British were a weak reed in North America, upon whom the Indians were unwise to rely. It cost them thousands of lives, including the life of Tecumseh himself. You're an ignorant bullshit artist.
