Melchior Hoffman had been imprisoned in Strassburg in 1533, and a new leader arose in the Netherlands--Jan Matthys, a baker of Haarlem. Under his guidance an energetic propaganda was carried on in the Dutch towns, and hundreds of converts were made. One hundred persons were baptized in one day in February (1534); before the end of March it was reported that two-thirds of the population in Monnikendam were Anabaptists; and a similar state of matters existed in many of the larger Dutch towns. Deventer, Zwolle, and Kampen were almost wholly Anabaptist. The Government made great exertions to crush the movement. Detachments of soldiers were divided into bands of fifteen or twenty, and patrolled the environs of the cities, making midnight visitations, and haling men and women to prison until the dungeons were overcrowded with captured Anabaptists. Attempts were made by the persecuted to leave the country for some more hospitable place where they could worship God in peace in the way their consciences directed them. East Friesland had once been a haven, but was so no longer. Münster offered a refuge. Ships were chartered,--thirty of them,--and the persecuted people proposed to sail round the north of Friesland, land at the mouth of the Ems, and travel to Münster by land.[245] The Emperor's ships intercepted the little fleet, sank five of the vessels with all the emigrants on board, and compelled the rest to return. The leaders found on board were decapitated, and their heads stuck on poles to warn others. Hundreds from the provinces of Guelderland and Holland attempted the journey by land. They piled their bits of poor furniture and bundles of clothes on waggons; some rode horses, most trudged on foot, the women and children, let us hope, getting an occasional ride on the waggons. Soldiers were sent to intercept them. The leaders were beheaded, the men mostly imprisoned, and the women and children sent back to their towns and villages.
