No one disputed that the privateers were a very important branch of the American navy; but they suffered under serious drawbacks, which left doubtful the balance of merits and defects. Perhaps their chief advantage compared with government vessels was their lightness,--a quality which no government would have carried to the same extent. The long-range pivot-gun was another invention of the privateer, peculiarly successful and easily adapted for government vessels. In other respects, the same number or even half the number of sloops-of-war would have probably inflicted greater injury at less cost. The “Argus” showed how this result could have been attained. The privateer’s first object was to save prizes; and in the effort to send captured vessels into port the privateer lost a large proportion by recapture. Down to the moment when Admiral Warren established his blockade of the American coast from New York southward, most of the prizes got to port. After that time the New England ports alone offered reasonable chance of safety, and privateering received a check.[436] During the war about twenty-five hundred vessels all told were captured from the British. Many were destroyed; many released as cartels; and of the remainder not less than seven hundred and fifty, probably one half the number sent to port, were recaptured by the British navy. Most of these were the prizes of privateers, and would have been destroyed had they been taken by government vessels. They were usually the most valuable prizes, so that the injury that might have been inflicted on British commerce was diminished nearly one half by the system which encouraged private war as a money-making speculation. Another objection was equally serious. Like all gambling ventures, privateering was not profitable. In the list of five hundred privateers furnished by the Navy Department,[437] three hundred were recorded as having never made a prize. Of the remainder, few made their expenses. One of the most successful cruises of the war was that of Joshua Barney on the Baltimore schooner “Rossie” at the outbreak of hostilities, when every prize reached port. Barney sent in prizes supposed to be worth fifteen hundred thousand dollars; but after paying charges and duties and selling the goods, he found that the profits were not sufficient to counterbalance the discomforts, and he refused to repeat the experiment. His experience was common. As early as November, 1812, the owners of twenty-four New York privateers sent to Congress a memorial declaring that the profits of private naval war were by no means equal to the hazards, and that the spirit of privateering stood in danger of extinction unless the government would consent in some manner to grant a bounty for the capture or destruction of the enemy’s property.
