§ 194. Since through adjudication by the Prize Courts the ownership of captured private enemy vessels becomes finally transferred to the belligerent whose forces made the capture, it is evident that after transfer the captured vessel as well as her cargo may be destroyed. On the other hand, it is likewise evident that, since a verdict of a Prize Court is necessary before the appropriation of the prize becomes final, a captured merchantman must not as a rule be destroyed instead of being conducted to the port of a Prize Court. There are, however, exceptions to the rule, but no unanimity exists in theory or practice as regards those exceptions. Whereas some[387] consider the destruction of a prize allowable only in case of imperative necessity, others[388] allow it in nearly every case of convenience. Thus, the Government of the United States of America, on the outbreak of war with England in 1812, instructed the commanders of her vessels to destroy at once all captures, the very valuable excepted, because a single cruiser, however successful, could man a few prizes only, but by destroying each capture would be able to continue capturing, and thereby constantly diminish the enemy merchant fleet.[389] During the Civil War in America the cruisers of the Southern Confederated States destroyed all enemy prizes because there was no port open for them to bring prizes to. And during the Russo-Japanese War, Russian cruisers destroyed twenty-one captured Japanese merchantmen.[390] According to British practice,[391] the captor is allowed to destroy the prize in only two cases--namely, first, when the prize is in such a condition as prevents her from being sent to any port of adjudication; and, secondly, when the capturing vessel is unable to spare a prize crew to navigate the prize into such a port. The _Règlement international des prises maritimes_ of the Institute of International Law enumerates in § 50 five cases in which destruction of the capture is allowed--namely (1) when the condition of the vessel and the weather make it impossible to keep the prize afloat; (2) when the vessel navigates so slowly that she cannot follow the captor and is therefore exposed to an easy recapture by the enemy; (3) when the approach of a superior enemy force creates the fear that the prize might be recaptured by the enemy; (4) when the captor cannot spare a prize crew; (5) when the port of adjudication to which the prize might be taken is too far from the spot where the capture was made. Be that as it may,[392] in every case of destruction of the vessel the captor must remove crew, ship papers, and, if possible, the cargo, before the destruction of the prize, and must afterwards send crew, papers, and cargo to a port of a Prize Court for the purpose of satisfying the latter that both the capture and the destruction were lawful.
