The whole force she brought over for this expedition consisted but of one hundred and forty knights;[32] for she trusted altogether in her cause and her friends.

With this slender attendance she went to Arundel, and was there received into the castle by the widow of the late King; while Earl Robert, accompanied only by twenty men, marched boldly to his own city of Gloucester, in order to raise forces for the Empress, where the townsmen turned out the King's garrison as soon as they heard of his approach.
[Footnote 32: In these times none served on horseback but gentlemen or knights, in right of their fiefs, or their representatives, called _Men-at-arms;_ and each of these was attended by at least two servants or retainers mounted and armed.

[D.S.]] King Stephen was not surprised at the news of the Empress's arrival, being a thing he had always counted upon, and was long preparing himself against.

He was glad to hear how ill she was provided, and resolved to use the opportunity of her brother's absence; for, hasting down to Arundel with a sufficient strength, he laid siege to the castle, in hopes, by securing her person, to put a speedy end to the war.
But there wanted not some very near about the King, who, favouring the party of Maud, had credit enough to prevail with him not to venture time and reputation against an impregnable fortress, but rather, by withdrawing his forces, permit her to retire to some less fortified place, where she might more easily fall into his hands.

This advice the King took against his own opinion; the Empress fled out of Arundel by night; and, after frequent shifting her stages through several towns, which had already declared in her favour, fixed herself at last at Lincoln; where, having all things provided necessary for her defence, she resolved to continue, and expect either a general revolt of the English to her side, or the decision of war between the King and her brother.
But Stephen, who had pursued the Empress from place to place, hearing she had shut herself up in Lincoln, resolved to give her no rest; and to help on his design, it fell out that the citizens in hatred to the Earl of Chester, who commanded there for the Empress, sent a private invitation to the King, with promise to deliver the town and their governor into his hands.
