Captain John Smith, Captain Christopher Newport and twenty other settlers decided to explore the general area of the Jamestown region. From June to September, they journeyed the entire length of the Chesapeake Bay and they witnessed the eastern shore of the bay, the Potomac River, the Great Falls, the Susquehanna River, the Rappahannock River, the York River and the Chesapeake River. Smith carefully drew a map of the entire area and called it a "Map of the Chesapeake." He sent it to England via Captain Newport, and it was later published in London. The courage and persistent hard work of the settlers and the leadership of Captain John Smith were invaluable. Captain John Smith maintained harmony in the Council, encouraged friendly relations with the Indians (eventually to the extent of getting corn, an absolute necessity, from them) and changed the "common store" policy to a "no work-no eat" policy which had most effective results on the indolent settlers. In 1608, he wrote a fascinating narration about the founding of the Virginia Colony which he entitled "A True Relation." He is sometimes referred to as the "Father of Virginia" because of his participation in so many activities: a governmental official (president of the Council from September 1608 to September 1609), a diplomat in his relations with the Indians, a leader in attempting to maintain peaceful, cooperative relations among the settlers themselves, an observing prisoner of the Indians (during which time he learned much of their culture and experienced the miraculous saving of his life by the Indian girl, Pocahontas) and a writer who tried to picture the happenings of the settlers in an enjoyable fashion.
