Commemorating the Sesquicentennial of the Maryland Natural Resources Police, theoldest statewide law enforcement agencyin Maryland and the fourth oldest conservation law enforcement agency in the country. It traces its origins to the Maryland Oyster Police Force, founded in 1868 with the appointment of its first commander, Hunter Davidson.
Fighting naturalist…nota common characterization to be sure, but history presents several military figures that have made significant contributions to natural science. Two of the more familiar are British Royal Navy Captain James Cook’s discoveries throughout the Pacific Ocean and the voyages of Captain John Smith, an early 17th century explorer with an impressive military resume famous for documenting the Chesapeake Bay.
In the United States, President Thomas Jefferson sent Captain Meriwether Lewis and Second Lieutenant William Clark, both Army officers, to explore the interior of the North American continent hopeful of finding an inland water route to the Pacific Ocean. They had additional instructions to record and retrieve samples of new species of plant and animal life. The U.S. Exploration Expedition, led by Navy Lieutenant Charles Wilkes, traveled throughout the South Pacific between 1838 and 1842 and brought back artifacts that became among the first to be displayed as part of the Smithsonian collection in Washington, D.C.
Courage, experience in logistics and organization, along with a calmness under pressure and knack for the ability to triumph through adversity are qualities that served them well as military officers. Equally important to their successes as naturalists were their desire to further the collective body of scientific knowledge and a personal pride in efforts to record, preserve, and even enhance the natural world through which they traveled.
One such man was Hunter Davidson. His legacy is part of the lore of the Maryland Department of Natural Resources as he became the first Commander of the State Oyster Police Force, forerunner of today’s Maryland Natural Resources Police. Unquestionably a warfighter first, and a prominent one at that, his efforts have had a long-lasting impact on natural resource conservation beyond what he might have personally imagined.
Born in Georgetown in 1826, Davidson earned his sea legs in the pre-Civil War Navy of the United States. He was an 1847graduate of the fledgling Naval Academy at Annapolis andwas present for operations aboardUSS PORTSMOUTHduring the War with Mexico. Subsequently he spent time in the 1850s assigned toUSS DALEinterdicting the slave trade off the African coast.
Davidson was on duty as an instructor at Annapolis in 1861 as the national crisis began to divide the states. Rear Admiral Robley Evans, a midshipman at the time but ultimately rising through the ranks to command President Theodore Roosevelt’s Great White Fleet, observed and admired Davidson for his integrity and professionalism during this tumultuous time in our nation’s history. He recalls in his autobiography:
“It was a time of great suspense for all hands; naturally the greatest strain fell on those in authority, but the midshipmen had their loads to bear as well. Many of us came from the South, and as the states, one after another either seceded or threatened to do so, we had to make up our minds what we were going to do. Conferences were frequent and serious, but never in one of them was there a disloyal word uttered. Every man followed the example set by the Southern men among the officers. So long as we were inside the Academy limits, or until our resignations were accepted, we were officers of the navy and would behave as such. Lieutenant Hunter Davidson, afterward the torpedo expert of the Confederacy, was probably more responsible for this position than any other man…”
Davidson cast his lot with the Confederacy. Rather than a seagoing career characterized by fleet engagements in battleships upon the oceans, his circumstances with the Confederate Navy dictated a different path. His wartime service focused on riverine operations for an under resourced and overmatched Confederate Navy, one whose tactics were characterized by the mining of waterways, technological innovation, harassment incidents and commerce-raiding.
Among his earliest assignments as a Confederate Naval Officer was aboardCSS VIRGINIA, formerly theUSS MERRIMACK, as a gunnery officer during the Battle of Hampton Roads in March 1862. He participated in the world’s first ever clash between ironclads during an encounter against theUSS MONITOR. This was the most famous maritime engagement of the Civil War and an important milestone during a time of transition from the age of sail with “wooden ships and iron men” to an age of steam powered vessels with armored plate, precision weapons and exploding shells.
Franklin Buchanan, who commandedVIRGINIAon the first day of the battle, specifically mentioned Davidson in his post-action report highlighting that“Lieutenant Davidson fought his guns with great precision. The muzzle of one of them was soon shot away. He continued, however, to fire it, though the woodwork around the port became ignited at each discharge. His buoyant cheerful bearing and voice were contagious and inspiring.”
Davidson later claimed several direct hits onUSS MINNESOTA,causing her to run aground.Partially due to Davidson’s expert gunnery and leadership during this battle in March 1862,VIRGINIAhanded the U.S. Navy the most devastating losses it would realize until the Japanese attacked Pearl Harbor in December 1941.
Following the Battle of Hampton Roads, Davidson was assigned to the James River Squadron both in command ofCSS TEASER, a former steam powered tug boat, and as assistant to Matthew Fountaine Maury doing experimental work with underwater mines (torpedoes). On Independence Day 1862, while serving as a floating observation balloon launch platform,TEASERwas captured after being hit by shells from two Union vessels includingMONITOR. As a testament to his daring and innovative spirit, Davidson’s private memorandum book was captured and contained, as described byMONITOR’s Acting Assistant Paymaster William Keeler:
“The private memorandum book of Hunter Davidson who was in command. He was one of the officers of the MERRIMAC & in this book was drafts of the MONITOR and sketches of the mode of our capture as they intended to attempt it. It was minute in all its details. We were to be bonded from four tugs at the same time (one of them was the TEASER) by men carrying turpentine, ladders, fireballs, wedges, sheets of metal, chloroform, etc…The names of the men were given, just what article each one was to carry, to what part of the MONITOR he was to go, etc… It even gave the men who were to carry matches & sand paper to rub them on.”
As part of his work with explosives, Davidson’s team developed an effective spar torpedo, essentially a contact bomb at the end of a pole, which he quickly decided to test in battle againstMINNESOTA, at that time berthed downriver at Newport News. With a small crew of daring men, he stealthily maneuvered the steam launchSQUIBamong the enemy fleet at night, locating the flagship and successfully detonating the spar torpedo causing significant, but not fatal, damage. This incident represented the first successful use of offensive torpedoes during the war without a simultaneous loss of the attacking party…lucky for Davidson!
SQUIB’sescape was harrowing, first traveling farther east to confound pursuers, and then returning westerly by cautiously proceeding at night and camouflaging the vessel in tributary creeks by day. This incident resulted in a promotion for Davidson from Lieutenant to Commander and accompanying mention in a report by the Confederate States Secretary of the Navy Stephen Mallory, stating“The cool daring, professional skill, and judgment exhibited by Lieutenant Davidson in this hazardous enterprise merit high commendation and honor upon the service of which he is a member.”
Davidson’s most impactful effort during the Civil War was in his role as Commander of the Confederate Submarine Battery Service, perfecting and operationalizing the concepts and work he started with his mentor, Maury, on the electric detonation of mines. As a direct route to the Confederate capital of Richmond, Virginia, the James River was a strategic military prize. In May 1864, the Union began a coordinated plan to capture Richmond with the North Atlantic Blockading Squadron sent up the James River with supplies and logistics support for land forces under the command of General Benjamin Franklin Butler.
Mindful of intelligence reporting the presence of underwater mines, the North’s forces were carefully preceded by mine-sweeping gunboats and troops searching the river banks for telltale wires and the necessary galvanic battery. Perfectly timing a detonation as theUSS COMMODORE JONESpassed directly over a mine, the vessel was completely destroyed by the explosion. Having taken place in full view of the North’s fleet, the threat of additional losses deterred them from further advancement up the river. The subsequent attack on Drury’s Bluff near Richmond by Butler’s forces was repulsed, most probably due to the fleet’s inability to provide support.
In an account published after the war in “Confederate Veteran” magazine, Davidson claimed that Secretary of the Navy Mallory wrote him after this incident and stated“I always considered your torpedo division as equal to any division in our Army.”High praise indeed!
A Naturalist’s Inclination
In the early 1850s before the Civil War, Davidson was assigned duty for several years with the Coast Survey, a predecessor of what became the National Oceanic and Atmospheric Administration. The U.S. Navy had a close relationship with the Coast Survey during this time with federal law requiring survey vessels to be crewed by Navy personnel when available. The purpose of the survey was to use scientific methods to chart the coastal areas of the country, making them safe for navigation and commerce. The data discerned and analyzed by the Coast Survey was vital, not only for commerce, but also for an understanding of conditions, including habitat, necessary to the work and interests of a naturalist.
Davidson no doubt found the knowledge gained from his years of survey work useful during his tenure commanding the Submarine Battery Service for the Confederacy. However, it was after the war, when his disloyalty to the Union disqualified him from further military service to the nation that he used this knowledge to great advantage. A perfect opportunity presented itself in the state of Maryland.
Chesapeake Bay is the largest estuary in the country with a watershed of more than 60,000 square miles. Salt water from the Atlantic Ocean mixes with fresh water from tidal rivers to produce an incredibly diverse and productive brackish habitat. The word “Chesapeake” may even come from a local Native American term for “Great Shellfish Bay.” Captain John Smith is often quoted as describing the great numbers of oysters that“lay thick as stones.”
For centuries, Chesapeake Bay oysters were harvested for local consumption. By the mid-1800s, harvested oysters could be canned for shipment to distant markets. Transportation networks and railways improved as cities matured, the growing taste for oysters seemed insatiable, and oysters found ready markets throughout the country. At first, the supply seemed as limitless as the demand, but that situation soon changed.
Maryland passed laws restricting harvest, New England watermen traveled to the Chesapeake as their own beds were depleted, the water boundary between Virginia and Maryland was in dispute, and local law enforcement of state restrictions was minimal to poor. As a result, in 1868 Maryland created the State Oyster Police Force and Hunter Davidson was selected its first commander. This period is known as the Oyster Wars.
Determined to make an immediate difference, Davidson hired experienced officers, acquired a number of vessels, issued orders, and armed his small fleet as best he could to include a12-pound cannon. His intrepid spirit and detailed efforts met with success. So much so that one of his more noteworthy adversaries, Gus Rice, planned and carried out an attack on his vessel,LEILA, intent upon murder.
“Shortly aftermidnightJanuary 28, 1871, a small boat left St. Michael’s, staying close to the shore to avoid being silhouetted on the open water. As thePirateseased their way through the ice cakes and approached the steamer, they discovered only one man on duty; they quickly knocked him unconscious with a culling hammer. When they arrived at Davidson’s cabin, they discovered that the door was locked, and as they struggled with it, they awakened the Captain. With hardly a moment to lose, Davidson leapt out of bed, grabbed his Colt revolver, and fired two shots through the door. The Pirates scrambled desperately back to their skiff and were rowing wildly for the shore when Davidson fixed them in the sight of his rifle. After a short burst of fire over their heads, the oystermen surrendered and Davidson’s men brought the criminals back toLEILAin shackles.”
Aside from the inroads Davidson made for Chesapeake Bay conservation law enforcement, he used his experience with the Coast Survey, analytical ability, and growing knowledge of the industry to authora reportto the Maryland General Assembly in 1870 making recommendations regarding oyster management issues that are astoundingly similar to the issues debated –though not so violently – today. His observations are astute for someone not trained as a scientist, though his recommendations take a strong anti-commercial industry tact perhaps due, at least partially, to the resistance met by his enforcement measures amongst oystermen.
He felt the oyster population depleted to the point he advocated for a three-year gear restriction moratorium on dredging (without a corresponding reduction of tonging) to remove harvest pressure in deep water areas and allow enough time for the existing spat set to grow to market size. For enforcement reasons, he also recommended no dredging be allowed at night. Further, he advocated for a time of year restriction on dredging to shorten the season to Sept. 1 through May 31, to allow more opportunity for reproduction success.
Keenly aware of a lack of resources necessary for adequate enforcement and understanding the profit margins then existing in each segment of the oyster supply chain, he proposed an increase of license fees for harvesters as well as a new carrying tax per bushel on “All persons engaged in packing, pickling, or opening Oysters for sale or transportation…”Insightfully, he also suggested the licensing and fee structure be identical to those imposed by Virginia so as not to exasperate the competition already felt between the two jurisdictions.
Davidson foresaw the tremendous opportunity for oyster aquaculture, pointing out the ideal environmental conditions and the sustainable nature of the endeavor.
“The most liberal encouragement should be given to persons to plant and cultivate the Oyster. I know of no enterprise which is more remunerative, and which need give less anxiety as to certainty of results, if ordinary personal attention is given to the business.Almost every bend of our shores, protected from the storms, is a little mine of wealth, if the efforts of our people can once be turned in that direction.”
Davidson did not hold back his frustration with certain members of the judiciary as he lamented a lack of success in prosecuting harvest restrictions which sound eerily similar to today.“Nearly all of these cases have first to go before the Justices of the Peace, whose total want of education,in some instances, renders them unable to comprehend a case, or pronounce an intelligent judgment.”
Davidson quit state service in 1872 as a result of his Oyster Police Force being used too often as a source of patronage for unqualified friends of politicians. For someone so mission-oriented and having made significant strides toward his goals, decisions that weakened the effectiveness of his command proved to be more than he could stand.
For the remainder of his professional career, he furthered both his warfighter credentials and naturalist reputation in South America. He founded the Argentine Navy’s Torpedo Division and then, once again –using the skills obtained during his formative years – performed the first detailed hydrographic surveys of Argentine waters including the Bahia Blanca Estuary and the Iguazu River and Falls.
Davidson died in Paraguay in 1913 at the age of 86.
