Exploration and fortification--these two terms are consistently linked in the papers on which the early English adventurers jotted notes for their guidance or for the instruction of their agents in America. The very first objective of the explorers was to locate a suitable site for fortification, in order that further explorations might be conducted from a secure base. The fortifications to be raised had to meet exacting standards, such as would be approved by the military engineers with whom the adventurers consulted along with the geographers, the cartographers, and the shipmasters who also possessed useful information. For these fortifications were intended to provide security not so much against the native Indian as against the ships and soldiers of Spain. Over the years there had been some debate as to how the fort might be best located, with the result that in 1607 it was decided to locate it some distance up a river that would afford navigation for an ocean-going vessel but would force the enemy to fight his way inland against the disadvantage of the warning that could be given by an outer guard at the mouth of the river. Such were the considerations that shaped the choice of Jamestown as the site of the first permanent English settlement in North America. To stand in the middle of the Jamestown peninsula for contemplation of its many disadvantages for the purposes of agricultural settlement, and even for the health of its people, is to lose sight of the main point. One should walk over against the river, and consider there the field of fire that was open for well placed guns.
And just what was the Jamestown fort supposed to guard? Was it the few acres of the modern county of James City, or the right of Englishmen to possess the Virginia peninsula, where so much of importance to our national history has found its place? Not at all. It was the right of Englishmen to be in North America, to fish the waters that lay off its coast, to trade with its inhabitants, and to exploit such other opportunities as an unexplored and undeveloped continent might offer. How far these opportunities might lead no one could tell in advance--perhaps even to China.
A trade with China had been a major objective of English adventure since the middle of the sixteenth century, when the Muscovy Company had had its origins in an attempt to find a northeast passage around the Scandinavian peninsula leading to Cathay--Marco Polo's fabulous kingdom of northern China. The explorers found instead a profitable trade with the territories of Ivan the Terrible, but the Muscovy merchants continued to support a variety of ventures seeking the establishment of an Oriental trade. Their agents looked into the possibilities of an overland trade through Russia to Cathay, and experimented none too profitably with a trans-Russia trade with Persia. They gave their support to renewed attempts to find a northeast passage and claimed a right of license for the numerous efforts that were made in Elizabeth's reign to find a northwest passage around or through North America. Failing in these efforts, the English merchants finally had challenged Portugal's monopoly of trade with the East Indies by way of the Cape of Good Hope. The East India Company, chartered by Elizabeth in 1600, had gotten off to a good start, and was destined to become one of the great empire builders of Britain's history. In 1606, however, the East India merchants had had just enough experience with the new trade to begin to appreciate some of its difficulties, as in the need to employ larger and more expensive ships than were standard in England's maritime trade and the great distance to China by way of the Cape of Good Hope. Perhaps, after all, some route through America might have the advantage over the Cape route. In the opinion of the late Sir William Foster, through many years historiographer of the India Office, this was a chief reason for the interest Sir Thomas Smith took in Virginia.
