Like Napoleon intended to invade England, but was never able to concentrate the ships and men to do so. He formed the 'Army of England', which was intended to be comprised of the 50,000 troops he estimated would do the job. These troops were never available, and he abandoned the plan England however, planned a defense, which relied on Fencibles, Yeomanry, Militia, and armed civilians in addition to Regular troops, and depended upon a 'scorched earth' strategy intended to deprive Napoleon's army of forage.
Eventually, the 'scorched earth' approach was abandoned in favour of a more conventional defense which was, of course, never used In 1797, however, the French did attempt to invade Ireland with 500 troops, but the ships carrying them were destroyed by a squadron under Edward Pellew.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
