A report from a correspondent on the Picardy front, dated May 6, 1918, described how the Germans launched a heavy gas attack against the Americans, sending over within a short period 15,000 shells, containing chiefly mustard gas. This attack was notable for a new German device, which is described as follows: The Germans introduced gas warfare, forcing modern soldiers to wear gas masks. Now after the use of masks has proved an effective weapon against gas they are using a new weapon to force the allied soldiers to take off masks that they may be easily killed by lethal phosgine and diphosgine gases. The weapon is nothing more or less than sneezing powder fired in high explosive shells. This powder percolates through mask respirators and brings on sneezing spells which lead the men to take off their masks and to receive the full effect of lethal gases. It has been used against the Americans. The method in use is to fire a number of sneezing powder shells just before a gas attack or to scatter them along among lethal gas shells. The German now uses his gases in four methods: First, clouds, which depend on a favorable wind; second, projectors, also depending on the wind; third, long-range artillery gas shells, and, fourth, hand grenades. Deadly gases, such as phosgine and diphosgine, are used in short-range guns, while neutralization gas, intended only to prevent activities of allied soldiers far back of the lines, is used at long range. Mustard gas is much used in this way. The latest perfection in the use of lethal gases is to fire twelve or more mortars shooting large-calibre shells at the same time by an electrical arrangement, thus producing great concentration. Russia Under Many Masters A Month's Events Amid the Chaos Produced by Bolshevist Misrule and German Invasion The State Department at Washington on May 16, 1918, published the text of a protest to Germany made by the Russian Government on April 26. The document opened with the following statement: "The Russian Government has taken every measure possible strictly to fulfill the Brest- Litovsk treaty from the Russian side, and in this way to secure for our people the chief aim of this treaty--a state of peace. But in reality no such state of peace exists." The message then enumerated the grievances of the Russians. It pointed out that by advancing upon Kursk and Voronezh the German and Ukrainian troops infringed the Russo-Ukrainian frontier line, "which was one-sidedly established by the Ukrainian Rada itself, and officially made known to us by the German Government." At the same time, the protest said, Russian military property in Finland was being seized by the White Guards, operating in agreement with German detachments and under instruction from the German staff.
