Lee saw how fishing in Northern waters had started America on its way to being a maritime power. In a series of letters to George Mason and others he expresses his opinions forcibly:
Our news here is most excellent; both from Williamsburg and from Richmond it comes that our countrymen have given the enemy in the South a complete overthrow.... Heaven grant it may be so. I shall then with infinite pleasure congratulate my friend on the recovery of his property, and our common country on so great a step towards really putting a period to the war. I think that in this case we may insist on our full share of the fishery, and the free navigation of the Mississippi. These are things of very great and lasting importance to America, the yielding of which will not procure the Congress thanks either from the present age or posterity.
I rejoice greatly at the news from South Carolina. God grant it may be true. If this should force the enemy to reason and to peace, would you give up the navigation of the Mississippi and our domestic fishery on the Banks of Newfoundland? The former almost infinitely depreciating our back country and the latter totally destroying us as a maritime power. That is taking the name of independence without the means of supporting it.
I rejoice exceedingly at our successes both in the North and in the South. If we continue to do thus, it will not be in the power of the execrable junto to prevent us from having a safe and honorable peace next winter. In this idea I shall ever include the fisheries and the navigation of the Mississippi. These, Sir, are the strong legs on which North America can alone walk securely in independence.
If you do not get a wise and very firm friend to negotiate the fishery, it is my clear opinion that it will be lost, and upon this principle that it is the interest of every European power to weaken us and strengthen themselves.
I heartily wish you success in your negotiations and that when you secure one valuable point for us (the fishery) that you will not less exert yourself for another very important object,—the free navigation of the Mississippi, provided guilty Britain should remain in possession of the Floridas.
Fishing as a matter of states' rights resulted in the pioneering Potomac River Compact of 1785, when representatives of Maryland and Virginia met under George Washington's sponsorship at Mt. Vernon to deal with fishing and tolls. Maryland owned the river to the Virginia shore line, and agreed to allow Virginians to fish in it in return for free entry of Maryland ships through the Virginia capes. The compact, in force to this day, was the first step taken in behalf of interstate commerce. With its example to follow, other states eased the barriers to their commercial interests, with immeasurable benefit to the Union.
Commercial fishing in Virginia was, as the century closed, on the verge of the stability it had sorely lacked. Its reliance on Indians for knowledge and skill, as in the first of the 17th century, was as dead as its reliance on England for manufactures in the last of the 18th. Just around the corner were railroads and steamboats with their comparatively swift transportation. Teeming cities needed to be fed, and after nearly two centuries of education in the ways of the Chesapeake Bay and its marine life, Virginia fishermen knew how to keep the markets stocked. In 1794 a French visitor, Moreau de Saint Méry, wrote:
Fish is the commodity that sells for a ridiculously low price in Norfolk. One can purchase weakfish weighing more than twenty pounds for 4 or 5 francs and sometimes one that weighs three times more for a gourde, 5 francs, 10 sous. Drum is also very cheap. Sturgeon, weighing up to 60 pounds, can be bought for 6 French sous a pound, about the same price paid for little codfish that are brought in alive and are delicious to eat. Shad is also plentiful there. In addition, one can get perch, porpoise, eels, leatherjackets, summer flounder, turbot, mullet, trout, blackfish, herring, sole, garfish, etc. In short, fish is so abundant in Norfolk that sometimes the police find it necessary to throw back into the water those that are not bought.
Herring fishing began to be abandoned by the planters, many of whom were up to their necks in a variety of enterprises, in favor of business men intending to specialize. Letters from a Virginia speculator, John F. Mercer, to Richard Sprigg, sketch the situation:
