After London by Richard Jefferies

The king's booth stood apart from the rest; it was not much larger, but properly thatched with straw, and the wide doorway hung with purple curtains. Two standards stood beside it; one much higher than the other. The tallest bore the ensign of the kingdom; the lesser, the king's own private banner as a knight. A breastwork encircled the booth, enclosing a space about seventy yards in diameter, with a fosse, and stakes so planted as to repel assailants. There was but one gateway, opposite the general camp, and this was guarded by soldiers fully armed. A knight on horseback in armour, except his helmet, rode slowly up and down before the gate; he was the officer of the guard. His retainers, some thirty or forty men, were drawn up close by.

A distance of fifty yards intervened between this entrenchment and the camp, and was kept clear. Within the entrenchment Felix could see a number of gentlemen, and several horses caparisoned, but from the absence of noise and the fact that everyone appeared to walk daintily and on tiptoe, he concluded that the king was still sleeping. The stream ran beside the entrenchment, and between it and the city; the king's quarters were at that corner of the camp highest up the brook, so that the water might not be fouled before it reached him.
