This picture shows a gunner carrying powder to one of the eighteen eleven-inch mortars, which did so much toward reducing Port Arthur. The gunner is hurrying from the bomb-proof magazine to the gun, carrying on his back in a cannister the charge of gunpowder that is to propel a 500-pound shell over the hills into the background and deal a smashing hammer-blow in the frowning face of a Russian fort. For the attack on stationary objects, such as forts, docks, buildings and ships at anchor, the Japanese Artillery Officers were provided with a map of the whole area of bombardment, which was laid out in squares, each square having its own number. The Japanese knew the exact location of every point of importance, having been in possession of Port Arthur at the end of their war with China, and having entertained an excellent bureau of intelligence during the two or three years of preparation for the war with Russia. Their shells were directed with mathematical accuracy to fall upon the particular spot to be hit.
