The arrival of the first English volunteers, under Thomas Morgan, in the Low Countries was, as fate willed it, most happily timed to synchronise with the movement that laid the foundation of Dutch Independence. In April 1572 an audacious enterprise of the fleet of Dutch privateers under the Count de la Marek had led to the surprise and capture of the town of Brill, a success which at once fired the train of revolt in the seven provinces north of the Waal and shook the hand of Spain from town after town first in Holland and Zealand, and later in Friesland, Gelderland, Utrecht, and Overyssel. The incident, which time was to prove so far reaching in its results, was a curious commentary on the latest phase of Elizabeth's policy. She had just reconciled herself with Alva and forbidden De la Marck's privateers to enter English ports: the sea-rover's reply was to beard Alva in his own stronghold and deal Elizabeth's friend a blow from which he never recovered. The whole island of Walcheren, excepting Middelburg, fell into the hands of the insurgents, and Alva, who was a splendid soldier, whatever his other failings, lost no time in attempting to recover the port of Flushing. By the irony of fate Morgan's volunteers arrived in the very nick of time to save it, and in the sally which brought them first face to face with the dreaded troops of Spain they made a brilliant beginning for the new British Army. Of the three hundred, fifty were killed outright in this action, the first of fifty thousand or twice fifty thousand who were to lay their bones in Holland during the next seventy years.
