Far more interesting than the campaigns of invasion in Henry’s earlier years, which had been led by Dorset in 1512, by the King himself in 1513, and by his brother-in-law of Suffolk in 1523, was the last military venture of the reign, the great scheme which started as a very ambitious project, the ‘Enterprise of Paris,’ a plan for crushing France in conjunction with the armies of the Emperor Charles, led by Charles himself, and which dwindled down into the siege of two isolated fortresses only a few miles within the French frontier.
