It soon offered. The Commandant of Louvestein[111] going to Heusden to raise recruits, Grotius' wife made a visit to his lady, and told her in conversation, that she was desirous of sending away a chest full of books, for her husband was so weak, it gave her great uneasiness to see him study with such application. Having thus prepared the Commandant's wife, she returned to her husband's apartment, and in concert with a valet and a maid, who were in the secret, shut him up in the chest. At the same time, that people might not be surprised at not seeing him, she spread a report of his being ill. Two soldiers carried the chest: one of them, finding it heavier than usual, said, There must be an Arminian in it: this was a kind of proverb that had lately come into use. Grotius' wife, who was present, answered with great coldness, There are indeed Arminian books in it. The chest was brought down on a ladder, with great difficulty. The soldier insisted on its being opened, to see what was in it; he even went and informed the Commandant's wife that the weight of the chest gave him reason to think there was something suspicious contained in it, and that it would be proper to have it opened. She would not; whether it was that she was willing to wink at the thing, or through negligence: she told him that Grotius' wife had assured her there was nothing but books in it; and that they might carry it to the boat. It is affirmed that a soldier's wife who was present, said there was more than one example of prisoners making their escape in boxes. The chest however was put into the boat, and Grotius' maid, who was in the secret, had orders to go with it to Gorcum, and put it into a house there. When it came to Gorcum, they wanted to put it on a sledge; but the maid telling the boatman there were some brittle things in it, and begging of him to take care how it was carried, it was put on a horse, and brought by two chairmen to David Dazelaer's, a friend of Grotius, and brother-in-law to Erpenius, having married his sister[112]. When every body was gone, the maid opened the chest. Grotius had felt no inconvenience in it, though its length was not above three feet and a half. He got out, dressed himself like a mason, with a rule and a trowel, and went by Dazelaer's back-door, through the market-place to the gate that leads to the river, and stept into a boat which carried him to Valvic in Brabant. At this place he made himself known to some Arminians; and hired a carriage to Antwerp, taking the necessary precautions not to be known by the way: it was not the Spaniards he feared, for there was then a truce between them and the United Provinces. He alighted at Antwerp at the house of Nicholas Grevincovius, who had been formerly a Minister at Amsterdam; and made himself known to no body but him. It was on the 22d of March, 1621, that Grotius thus recovered his liberty.
