Sneezing Powder in Gas Attacks

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.
