British submarines have been extremely active in the Baltic, and
in some places seem to have produced paralysis among shipping, At least one German destroyer has been sunk, but most of the German losses are among transports and merchant ships carrying supplies. The crews of the merchantmen have been warned in every case and enabled to escape. There has been no loss of non-combatant life. In ene case the crew of a British submarine took a captured vessel a hundred and sixty miles to Reval—a proof of the extraordinary boldness with which our submarines are acting. Altogether, about twenty-five merchant ships and five trans- ports are known to have been sunk during the past three or
four weeks. At one time it was assumed to be impossible for our submarines to penetrate or keep the Baltic with its narrow entrances and complicated and shoal waters. Truly the Navy has created for itself a sphere of activity which seems to be the only variation possible from its general role of passive domination.
