William felt himself to be month by month losing power.

The action he was at last compelled to take, in rescuing Ghent from the hands of the ultra-democratic Calvinist party and in expelling De Ryhove and De Hembyze, caused him to be denounced as "a papist at heart." Indeed the bigots of both creeds in that age of intolerance and persecution were utterly unable to understand his attitude, and could only attribute it to a lack of any sincere religious belief at all.

Farnese, meanwhile, whose genius for Machiavellian statesmanship was as remarkable as those gifts for leadership in war which entitled him to rank as the first general of his time, was a man who never failed to take full advantage of the mistakes and weaknesses of his opponents.
