But the period of patient waiting was now at an end. Bacon and his men were in possession of all Virginia west of the Chesapeake Bay. The immediate question was how to defend it against the governor and perhaps an expedition from England. For this the control of the water was vital. The four great rivers gave easy access to the heart of the colony to an enemy fleet, but were serious obstacles to moving troops by land. Without war vessels it would be necessary for Bacon to divide his little army into numerous widely separated detachments in order to defend hundreds of miles of shore.
Lying in the James River were three merchantmen, the _Honour and Dorothy_, the _Rebecca_, commanded by Captain Larrimore, and another _Rebecca_, commanded by Captain Eveling. On August 1 Giles Bland and William Carver, the latter "an able mariner and soldier," rowed out to Larrimore's ship, and though fired on, captured her. They then drew her up at Jamestown and mounted several guns on her from the fort. In the meanwhile Bacon, thinking Berkeley might be aboard Eveling's vessel, demanded permission to search her. But Eveling refused, calling him a rebel and naming him "Oliver Bacon", and before Larrimore's vessel could attack him, weighed anchor, slipped down the river, and headed for England.
Though disappointed at Eveling's escape Bland and Carver, with the _Rebecca_, a small bark, and a sloop, carrying a force of two hundred and fifty men, stationed themselves at the mouth of the James, ready to seize and to press into service any incoming vessels. But they made the mistake of moving across the bay and anchoring off Accomac to treat with the governor. Carver, with 160 men, came ashore in a pinnace. Berkeley tried to persuade him to desert Bacon, but he replied that "if he served the devil he would be true to his trust."
Berkeley ordered him to be gone within eight hours, but contrary winds sprang up so that he had to delay. This Berkeley thought Carver was glad of, since it gave him an opportunity to wean his soldiers away from him. But it proved a godsend for Berkeley. At about midnight a message came to him from Captain Larrimore, explaining that he and his crew served under duress, that there were only forty soldiers left on board the _Rebecca_, and that if he could send thirty or forty gentlemen to the ship, he was sure they, with the help of the sailors, could retake her.
