Summary
The year 1778 was pivotal for American Revolutionary War financing. The Franco-American Treaty of Alliance signed on February 6, 1778, fundamentally transformed the colonists’ access to capital and supplies. Benjamin Franklin and Silas Deane’s diplomatic mission secured French loans, subsidies, and credit that proved indispensable to sustaining the Continental Army’s operations. Simultaneously, the Continental Congress attempted to finance the war through currency issuance, privateering authorization, and domestic taxation, though these measures increasingly strained the colonial economy.
By 1778, French financial backing had become the Revolution’s lifeblood. The Treaty of Alliance was accompanied by a Treaty of Amity and Commerce that opened French ports to American merchants and privateers, disrupting British supply chains while enriching American commerce raiders. French loans began flowing immediately: the French crown eventually committed over 1.3 billion livres (approximately $6 billion in 2020 dollars) over the entire war, with substantial portions advanced in 1778–1779. These funds purchased military supplies—cannon, muskets, gunpowder—that the Continental Congress could never have procured domestically.
The Continental dollar, however, suffered catastrophic inflation. The Second Continental Congress had begun issuing paper currency in 1775 to fund military operations, but by 1778 the currency had depreciated sharply. Excessive printing, counterfeiting, and lack of fiscal coordination among the states rendered Continental dollars nearly worthless by year’s end, trading at only one-seventh to one-fifth of face value. This forced the government to rely almost entirely on French loans and goods, rather than domestically financed procurement.
Privateering became a critical economic weapon in 1778. Congress issued letters of marque authorizing armed merchant vessels to attack British shipping. These privateers seized British merchant ships and their cargo, enriching their owners and crews while disrupting British commerce. The legal plunder sustained private capital formation in America and provided an alternative to conventional taxation, as successful privateering ventures distributed profits to shareholders and crews rather than flowing to state treasuries. However, the economic gains were unevenly distributed and did not substitute for systemic public finance.
By the end of 1778, the financial situation was precarious despite French support. The Continental dollar crisis, mounting war debt, and reliance on foreign loans foreshadowed the fiscal instability that would plague the early American republic and contributed to the urgent need for constitutional reform embodied in the Constitution of 1787.
Continental Currency: The Inflation Crisis of 1778
By 1778, the Continental dollar — first issued in June 1775 — had entered acute depreciation. Exchange rates against a silver dollar fell from roughly 1.25:1 in early 1777 to between 5:1 and 7:1 by December 1778; in some markets rates reached 6:1 as early as April 1778. Congress had authorized cumulative currency emissions approaching $100 million nominal by year’s end with no mechanism to retire bills through taxation, since the draft Articles of Confederation denied Congress taxing power. A deliberate British counterfeiting campaign operated from New York City under Governor William Tryon, flooding Patriot markets with high-fidelity forged bills and accelerating the currency’s collapse. For the full account of this monetary crisis, see Continental Dollar Crisis of 1778.
The depreciation hit soldiers and suppliers hardest. Troops at Valley Forge over the winter of 1777–1778 received wages in Continental dollars that purchased a fraction of their nominal value; farmers and merchants increasingly refused Continental currency outright or demanded wildly inflated prices. Congress responded with regional price conventions in 1777–1778 setting maximum prices for commodities, but enforcement proved impossible without federal executive authority.
French Loans and the Franco-American Alliance
The Treaty of Alliance signed February 6, 1778, unlocked formal French financial support that transformed American war-making capacity. Before formal recognition, France had channeled clandestine aid through the fictitious firm Rodrigue Hortalez et Cie, established in 1776 by playwright Pierre-Augustin Caron de Beaumarchais with a 1-million-livre royal subsidy. After the alliance, France opened the royal treasury directly: the first post-alliance loan in 1778 amounted to 3 million livres, with additional royal subsidies totaling 6 million livres by year’s end. Over the full war France committed approximately 1.3 billion livres — equivalent to roughly $6 billion in 2020 dollars — in loans and subsidies.
Benjamin Franklin, who cultivated deep social and intellectual ties among Versailles officials and was celebrated in Paris salons as the embodiment of republican virtue, was the indispensable architect of these negotiations. His personal credibility reassured French lenders that American obligations would eventually be honored. The French also shipped military supplies directly: cannon, muskets, gunpowder, and uniforms organized through Silas Deane’s logistical network reached the Continental Army in time for the post-Valley Forge 1778 campaign season. Without French materiel, the reformed army that departed Valley Forge in June 1778 could not have fought effectively at the Battle of Monmouth.
Robert Morris and Domestic Private Finance
Robert Morris (1734–1806), Philadelphia merchant and Continental Congress delegate throughout 1778, functioned as the Revolution’s dominant domestic financier before Congress formally appointed him Superintendent of Finance in 1781. In 1778 he operated informally, using his own credit and business networks to supply the army with provisions when public funds were exhausted or refused. His personal wealth and commercial reputation let him borrow on favorable terms from private Philadelphia lenders, providing a critical supplement to French loans during the 1778 campaign season. He organized procurement contracts and arranged payment in specie or negotiable bills when Continental dollars were unacceptable to suppliers.
Morris’s 1778 activities exposed the structural dependency on private credit that characterized revolutionary finance. Congress lacked compulsory taxation power, so voluntary cooperation from merchants like Morris became indispensable — a dependence that foreshadowed his later arguments for a stronger federal government, arguments that contributed to the movement toward the Constitutional Convention of 1787.
Privateering as Economic Warfare
Congress issued letters of marque throughout 1778, authorizing armed merchant vessels to seize British ships and cargo. American privateers operated from ports in Massachusetts, Rhode Island, and South Carolina, targeting British merchant vessels across the Atlantic and Caribbean. The Treaty of Amity and Commerce opened French and French colonial ports to American prize ships, providing legal havens where captured vessels could be adjudicated and sold — an arrangement that dramatically increased privateering profitability and attracted additional private capital investment. American privateers collectively captured or destroyed an estimated 600 or more British vessels during the war’s peak years (1778–1781), inflicting tens of millions of pounds in losses on British commerce.
The economic gains, however, flowed to private investors and crews rather than to public treasuries. Congress received only nominal admiralty shares insufficient to fund operations. Privateering also interacted with trade disruptions in complicated ways: British naval countermeasures penalized legitimate American shipping while the legal plunder enriched a merchant class whose interests were not always aligned with the Continental war effort. The Carlisle Peace Commission’s 1778 overtures were partly designed to separate this commercially minded class from the Patriot cause, offering trade concessions that might entice merchants to negotiate a settlement short of independence.
Significance
The financing mechanisms established in 1778—French loans, privateering, and Continental currency—determined whether the Revolutionary War could continue beyond its first years. Without French credit, the Continental Army could not have sustained operations from Valley Forge through Yorktown. The collapse of the Continental dollar, conversely, demonstrated the limits of paper money without backing and the necessity of international creditworthiness. The economic dependency on France created political obligations that would shape early American foreign policy and contributed to the financial crisis of the 1780s that necessitated the Constitutional Convention. Privateering, while profitable for individuals, failed to provide stable public revenue and underscored the structural weakness of the early American state in mobilizing its economic resources for military conflict.
