French invasion of Portugal and Spain 1807-1808

The French invasion of Portugal of November 1807 was the first campaign of what would become the Peninsular War.
The Peninsular War was one of Napoleon’s greatest blunders, leading to seven years of warfare and ending with an invasion of France, but it began with a an almost effortless invasion of Spain, which saw the occupation of Madrid, Old Castile and the fortresses on the Pyrenees, and was followed by a cynical but well managed abduction of the Spanish royal family.
