Sir Thomas Cecil was sent out at once as governor of Brill, and Sir Philip Sidney as governor of Flushing, these towns being handed over to England as guarantees by the Dutch. These two officers, with bodies of troops to serve as garrisons, took charge of their respective fortresses in November. Orders were issued for the raising of an army for service in the Low Countries, and Dudley, Earl of Leicester, was appointed by the queen to its command. The decision of the queen was received with enthusiasm in England as well as in Holland, and although the Earl of Leicester was not personally popular, volunteers flocked to his standard.

Breakfast at Hedingham Rectory had been set at an earlier hour than usual on the 6th of December, 1585. There was an unusual stir and excitement in the village, for young Mr. Francis Vere, cousin of the Earl of Oxford, lord of Hedingham and of all the surrounding country, was to start that morning to ride to Colchester, there to join the Earl of Leicester and his following as a volunteer. As soon as breakfast was over young Geoffrey and Lionel Vickars, boys of fourteen and thirteen years old, proceeded to the castle close by, and there mounted the horses provided for them, and rode with Francis Vere to Colchester.
