the French frontier in Artois and Hainault,
apparently threatening Bergen-op-Zoom and other cities in South Holland,
but in reality preparing to invade France. The Duke of Mayenne, who had
assumed the title of lieutenant-general of that kingdom, had already
visited him at Brussels in order to arrange the plan of the campaign.

While these measures were in preparation, an opportunity was likely to be
afforded to the Netherlanders of striking a blow or two for liberty and
independence; now that all the force that possibly could be spared was to
be withdrawn by their oppressors and to be used for the subjugation of
their neighbours. The question was whether there would be a statesman and
a soldier ready to make use of this golden opportunity.

There was a statesman ripe and able who, since the death of the Taciturn,
had been growing steadily in the estimation of his countrymen and who
already was paramount in the councils of the States-General. There was a
soldier, still very young, who was possessed of the strongest hereditary
claims to the confidence and affection of the United Provinces and who
had been passing a studious youth in making himself worthy of his father
and his country. Fortunately, too, the statesman and the soldier were
working most harmoniously together. John of Olden-Barneveld, with his
great experience and vast and steady intellect, stood side by side with
young Maurice of Nassau at this important crisis in the history of the
new commonwealth.

At length the twig was becoming the tree--'tandem fit surculus
arbor'--according to the device assumed by the son of William the Silent
after his father's death.

The Netherlands had sore need of a practical soldier to contend with the
scientific and professional tyrants against whom they had so long been
struggling, and Maurice, although so young, was pre-eminently a practical
man. He was no enthusiast; he was no poet. He was at that period
certainly no politician. Not often at the age of twenty has a man devoted
himself for years to pure mathematics for the purpose of saving his
country. Yet this was Maurice's scheme. Four years long and more, when
most other youths in his position and at that epoch would have been
alternating between frivolous pleasures and brilliant exploits in the
field, the young prince had spent laborious days and nights with the
learned Simon Stevinus of Bruges. The scientific work which they composed
in common, the credit of which th
