The Chesapeake Bay, where the Jamestown colonist George Percy wrote of finding, in April 1607, mussels and oysters that "lay on the ground as thick as stones,"[1] became the scene of a long and violent conflict over a natural resource. For nearly a century following the Civil War,[2] the waters of the Chesapeake echoed with gunfire as watermen, pirates, and law enforcement clashed in what history remembers as the Oyster Wars—a period of violence, greed, and lawlessness.
Setting the Stage: Post-Civil War Chesapeake
The end of the Civil War in 1865 transformed the Chesapeake Bay region in unexpected ways. As historian John R. Wennersten tells it, the war created a lot of disposable income, people began looking for status foods, and the Baltimore and Ohio Railroad and the development of canning let the Chesapeake meet the demand.[3]
Oysters that had once been thought fit only for the poor man's pot became a commodity that "created a boom reminiscent of a gold rush," in Wennersten's words.[3] The Chesapeake Bay Program puts the harvest from the Bay at more than 1.5 million bushels a year in the 1850s and at 20 million three decades later.[4] For Maryland alone, fisheries scientists Victor Kennedy and Linda Breisch give an estimate of about 14 million bushels for 1875 and a peak of about 15 million bushels in the 1884-85 season. They caution that harvest figures from most of the nineteenth century are gross estimates rather than counts.[5]
Towns like Crisfield on Maryland's Eastern Shore were transformed. After John Crisfield, the president of the Eastern Shore Railroad, got a rail spur to the town, "Crisfield became a city of oysters." In 1872, Wennersten wrote, the town "had the largest oyster trade in the state and provided employment for over six hundred sailing vessels."[3] It teemed with oystermen, merchants, and immigrants, but also with gamblers and prostitutes. The boxing ring in a local saloon hosted no-holds-barred fights between watermen from Virginia and from Maryland's Smith Island,[3] setting the tone for the violence to come.
Maryland had been legislating oysters for decades by then. Its first oyster law, passed in 1820, prohibited dredging and barred carrying oysters out of the state in vessels not wholly owned by Maryland residents. In 1865 the General Assembly abolished the old oyster laws and enacted a new code built on a statewide license system for tongers, scrapers, and dredgers. Many oystermen refused to buy licenses or to follow the code's other provisions,[5] and the conflict that followed is what we now call the Oyster Wars.
Tongers vs. Dredgers: A Technology Clash
At the heart of the Oyster Wars lay a fundamental dispute over harvesting methods that divided watermen into two hostile camps: tongers and dredgers.
Tongers worked the shallower waters from small boats that generally carried a couple of men, one handling the long tongs and one culling the catch. Dredgers used larger boats in deeper water and could take far more with the scoops they dragged across the oyster beds.[3] Maryland's 1820 law had banned dredging outright. The 1865 code made large dredges legal again after 45 years, in part because oysters in water deeper than 23 feet were out of reach of hand tongs and demand was rising quickly.[5]
Virginia had passed its own anti-dredging law in 1811, meant to protect its tongers from Maryland and New England dredgers.[2] New England's oyster beds were already badly depleted by then, and dredge schooners from Connecticut had been sailing south for oysters since about 1808.[5]
The economic disparity was stark. By the late 1860s the captain of a dredge boat could earn $2,000 a year at a time when most Marylanders earned $500 or less, and dredgers began moving into waters that tongers considered theirs.[3] The market kept growing: the number of oyster packing and canning houses in Baltimore rose from one in 1834 to 80 in 1868.[5]
This wasn't merely a dispute about fishing methods—it was a clash between watermen working the shallows by hand and crews equipped to take oysters on a much larger scale. People resorted to guns, and by Wennersten's account watermen were turning up dead in the bay.[3]
Night Raids and Gunfights on the Bay
The Oyster Wars earned their name through outbreaks of genuine combat on the Chesapeake's waters. Pirates—as the newspapers of the day called dredgers who worked forbidden ground—went armed. In February 1884 the New-York Tribune described a fleet of about twenty dredge boats on Maryland's Honga River carrying a hundred men with rifles, muskets, and pistols.[6]
These weren't always isolated poachers. In November 1888 a Baltimore dispatch printed in Washington's Evening Star reported that the dredgers on the Little Choptank River had joined forces, were well supplied with ammunition, openly defied the state authorities, and kept one vessel on guard duty at the entrance to the oyster ground.[7]
Joseph Becker's 1879 wood engraving shows the difficulties of oyster harvesting in the Chesapeake,[3] but an image of the work can't convey the violence that erupted on the bay. Confrontations between dredgers and the state's enforcement vessels escalated to exchanges of gunfire, and the police boats were often outnumbered.
Legal watermen found themselves caught in the crossfire, sometimes literally. The same 1888 report said that tongers working on the Little Choptank during the fight were shot at repeatedly and had to lie flat in their boats, and that afterward some were afraid to go back to work.[7]
Shanghaiing Workers: The Dark Underside
The violence of the Oyster Wars extended beyond gunfights on the water. The practice of "shanghaiing"—forcibly putting men to work on oyster boats—added a sinister dimension to the conflict.
Labor was short, and unscrupulous captains were not above stealing people, Wennersten says. The victims were often immigrants arriving in Baltimore. Once aboard, they faced beatings and the withholding of their wages, and sometimes, Wennersten adds, they "drowned when they caught the boom."[3]
The abuse became notorious enough that the Maryland German Society sent a detective to investigate the mistreatment and murder of a German immigrant by a Chesapeake captain.[3]
The Oyster Navy Forms: Maryland Fights Back
Faced with widespread defiance of the 1865 license law, Maryland took extraordinary action. In 1868 the state established a State Fishery Force, popularly known as the "Oyster Navy" or "Oyster Police."[5] Its first commander was Hunter Davidson, an 1847 Naval Academy graduate who had served as a Confederate naval officer. The Maryland Department of Natural Resources traces today's Natural Resources Police to that force and describes it as the oldest statewide law enforcement agency in Maryland and the fourth oldest conservation law enforcement agency in the country.[8]
The force started small: a steamer and two sailing vessels. By 1894 it had grown to two steamers, eleven sailing vessels, eight smaller county boats, and 120 men.[5] Davidson armed his fleet as best he could, including with a 12-pound cannon.[8] In his appeals to the legislature for more money and better boats, he called the watermen "reckless of consequences." In 1871 a dredger named Gus Rice tried and failed to murder him.[3] Davidson left state service in 1872, frustrated that the force was being used as a source of political patronage.[8]
The odds stayed daunting. In November 1888, after dredgers overpowered a police sloop on the Little Choptank, Annapolis's Evening Capital reported that Governor Jackson and Colonel Baughman went to Washington to ask the Secretary of the Navy for cannon for the Maryland oyster navy, and were told they could have whatever equipment they wanted.[9]
The patrol boats met resistance from the start. The license law was unpopular with oystermen, and the armed vessels patrolled the Bay and its tributaries with varying degrees of success at first.[5]
Famous Incidents: When the Bay Ran Red
Several confrontations during the Oyster Wars achieved particular notoriety, reported in newspapers well beyond Maryland:
The Honga River Fight (1884): In early February 1884 the State Oyster Police sloop Julia Hamilton, under Captain John H. Insley, confronted a fleet of dredgers working illegal ground in the Honga River (the "Hungers River" of the New-York Tribune's dispatch). By the Tribune's account the dredgers answered his call to surrender with a volley that cut up the sloop's rigging, then boarded her and traded shots with the crew below deck for half an hour. One dredger was killed before a truce was declared and the Hamilton withdrew. Insley refused to attack again, and Governor McLane ordered the police steamer Leila to the scene and appointed a new commander for the sloop.[6]
The Defeat of the Groome (1888): In November 1888 the police sloop E. B. Groome was overpowered on the Little Choptank River. The Evening Capital reported that the sloop's guns were taken by dredgers during a fight on November 22, and that about a week later the steamer Governor McLane delivered borrowed arms and ammunition to Captain Benjamin L. Keene, who had been placed in temporary command.[9] The Evening Star's dispatch said the state crews were demoralized, that many of the men had resigned, and that two dredging vessels had run aground while chasing the sloop.[7]
Virginia's Battles (1882-1884): In February 1882 Virginia Governor William E. Cameron commandeered two ships, the Victoria J. Peed and the Louisa, loaded them with state militia from Norfolk and Richmond, and went after the dredgers himself. According to the Library of Virginia, he apprehended forty-six illegal dredgers and captured seven boats, but the prosecutions and forfeitures did not hold up in court, and his next raid was less successful. In 1884 Virginia created the Board of the Chesapeake and its Tributaries and gave the state an oyster navy of its own.[2]
These incidents weren't isolated events. Kennedy and Breisch write that Maryland's force fought a number of pitched battles with defiant dredgers, notably around 1888, and that the sinking of dredge boats by cannon fire and the deaths of some offenders led to fewer open violations.[5]
The fighting did not end with the nineteenth century. On the Potomac River, which the two states had shared under the Compact of 1785, rising oyster prices after World War II brought new trouble, and a shooting war broke out between Maryland's Tidewater Fisheries Commission police and Virginia dredgers.[10] The Library of Virginia records the last casualty of the Oyster Wars in 1959, when Maryland oyster police shot Berkeley Muse for illegally dredging off Swan's Point.[2] The Potomac River Compact of 1958 replaced the 1785 agreement and created the Potomac River Fisheries Commission, which describes its own founding as a direct response to the battles between fishermen and law enforcement in the late 1940s and most of the 1950s. President John F. Kennedy signed the enabling legislation in December 1962, and the commission first met on January 10, 1963.[11]
Legacy in Modern Regulations: Lessons from the Wars
The Oyster Wars left an indelible mark on the Chesapeake Bay region, shaping oyster management policies that persist to this day. The century of conflict taught hard lessons about resource management, enforcement, and sustainability.
Maryland's rules on dredging evolved over time. For roughly a century the state allowed dredging only from a moving sailboat, an approach that Maryland Sea Grant's Chesapeake Quarterly sums up as saving oysters by making oystermen work hard. Skipjacks—the single-masted sailing craft that appeared in the 1890s—were built for that work; perhaps 700 were built, most of them between 1891 and 1916. The law later allowed two "push days" a week, when a small motor yawl boat could push the skipjack across the oyster grounds, and power dredging was opened in a few restricted areas in the late 1990s. By 1999 fewer than a dozen skipjacks were still working.[12]
The idea behind that first 1820 law proved durable too. Kennedy and Breisch count the belief that Maryland's natural oyster beds belong to the people of Maryland, to be worked by Maryland citizens only, among the convictions that shaped the state's oyster legislation, along with oystermen's long opposition to private leasing of oyster ground.[5]
Perhaps most significantly, the era showed what heavy exploitation could do. Maryland's catch declined after the 1885 peak.[5] Disease followed: Dermo was discovered in the Bay in 1949 and MSX a decade later.[4] NOAA Fisheries says only about 1 percent of the native oyster population remains, and the Chesapeake Bay Program attributes the decline to historic over-harvesting, disease, pollution, and habitat loss.[13][4]
Modern management reflects that history. Today's oyster wars, Wennersten says, are against parasites and pollution.[3] NOAA and its Chesapeake Bay Program partners set out to restore oyster reefs in 10 tributaries by the end of 2025 and report that they have done so: those tributaries now hold more than 2,400 acres of healthy reef, about 1,900 acres of it actively restored.[13]
Oyster farming is another change. The Bay Program describes oyster aquaculture as big business in Chesapeake waters, alongside a wild harvest that continues in both Maryland and Virginia.[4] Our guide to how oysters are farmed explains the methods.
Oysters are now valued for more than what they fetch at market. They are filter feeders, and their reefs shelter fish and invertebrates. The Bay Program says a single oyster can filter more than 50 gallons of water a day under certain conditions, a figure that is a ceiling rather than a typical rate (see what oysters eat). It estimates that in the late nineteenth century the Bay's oysters could filter a volume of water equal to the entire Bay in three or four days, and that today's population takes nearly a year.[4]
Yet challenges remain. As Wennersten observed, "Everyone wants to save the bay, but no one wants to be inconvenienced" to do it.[3] The tension between economic interests and conservation that sparked the Oyster Wars continues in different forms, though today's debates occur in legislative chambers rather than at gunpoint on dark waters.
Key Takeaways
- The Oyster Wars (roughly 1865-1959) were nearly a century of conflict over Chesapeake Bay oysters, driven by post-Civil War demand that created a "gold rush" atmosphere. Maryland's harvest peaked at about 15 million bushels in the mid-1880s.
- Technology and regulation clashed when Maryland's 1865 code licensed tongers and dredgers alike. Dredgers pushed into waters that tongers considered theirs, and many oystermen ignored the new law.
- Genuine warfare erupted on the bay, with armed dredgers fighting Maryland's Oyster Navy (founded 1868, the forerunner of today's Maryland Natural Resources Police), while shanghaied immigrants supplied forced labor on some boats.
- The conflict's legacy shaped modern oyster management, from a century of sail-only dredging in Maryland to the 1958 Potomac River Compact. Over-harvesting, disease, pollution, and habitat loss left the bay with about 1 percent of its native oyster population.
- Contemporary restoration efforts reflect hard-learned lessons: reefs have been restored in 10 Chesapeake tributaries, covering more than 2,400 acres, and oyster farming now operates alongside the wild harvest.
