g the highest professors of the new school. It was the
object of Maurice, who knew himself on the whole outnumbered, to divine
his adversary's intentions. Spinola was supposed to be aiming at Sluys,
at Grave, at Bergen-op-Zoom, possibly even at some more remote city, like
Rheinberg, while rumours as to his designs, flying directly from his
camp, were as thick as birds in the air. They were let loose on purpose
by the artful Genoese, who all the time had a distinct and definite plan
which was not yet suspected. The dilatoriness of the campaign was
exasperating. It might be thought that the war was to last another half
century, from the excessive inertness of both parties. The armies had all
gone into winter quarters in the previous November, Spinola had spent
nearly six months in Spain, midsummer had came and gone, and still
Maurice was at Watervliet, guessing at his adversary's first move. On the
whole, he had inclined to suspect a design upon Rheinberg, and had
accordingly sent his brother Henry with a detachment to strengthen the
garrison of that place. On the 1st of August however he learned that
Spinola had crossed the Meuse and the Rhine, with ten thousand foot and
three thousand horse, and that leaving Count Bucquoy with six thousand
foot and one thousand five hundred horse in the neighbourhood of the
Rhine, to guard a couple of redoubts which had been constructed for a
basis at Kaiserswerth, he was marching with all possible despatch towards
Friesland and Groningen.

The Catholic general had concealed his design in a masterly manner. He
had detained Maurice in the isle of Cadzand, the States still dreaming of
a victorious invasion on their part of obedient Flanders, and the
stadholder hesitating to quit his position of inactive observation, lest
the moment his back was turned the rapid Spinola might whirl down upon
Sluys, that most precious and skilfully acquired possession of the
republic, when lo! his formidable antagonist was marching in force upon
what the prince well knew to be her most important and least guarded
frontier.

On the 8th August the Catholic general was before Olden-zaal which he
took in three days, and then advanced to Lingen. Should that place
fall--and the city was known to be most inadequately garrisoned and
supplied--it would be easy for the foe to reduce Coeworden, and so seize
the famous pass over the Bourtanger Morass, march straight to
Embden--then in a state of municipal revolution o
