Immense preparations were made in France for this expedition.

In September, 1386, there were collected in the port of Ecluse (Sluys) and at sea, between Sluys and Blankenberg, thirteen hundred and eighty-seven vessels, according to some, and according to others only nine hundred, large and small; and Oliver de Clisson had caused to be built at Trdguier, in Brittany, a wooden town which was to be transported to England and rebuilt after landing, "in such sort," says Froissart, "that the lords might lodge therein and retire at night, so as to be in safety from sudden awakenings, and sleep in greater security." Equal care was taken in the matter of supplies.

"Whoever had been at that time at Bruges, or the Dam, or the Sluys would have seen how ships and vessels were being laden by torchlight, with hay in casks, biscuits in sacks, onions, peas, beans, barley, oats, candles, gaiters, shoes, boots, spurs, iron, nails, culinary utensils, and all things that can be used for the service of man." Search was made everywhere for the various supplies, and they were very dear.

"If you want us and our service," said the Hollanders, "pay us on the nail; otherwise we will be neutral." To the intelligent foresight shown in these preparations was added useless magnificence.

"On the masts was nothing to be seen but paintings and gildings; everything was emblazoned and covered with armorial bearings.
