Mustard Gas Deployment

Mustard gas was one of the deadliest weapons of World War I. This devilish weapon claimed even more lives than the infamous chlorine and phosgene.

Mustard gas was less lethal than phosgene or chlorine gas, but it claimed so many lives because its effects lingered.

Phosgene and chlorine are poison gases heavily affected by the wind. Though highly effective at killing people... depending on the weather, they can blow away in just a few hours.

That’s because both of these poison gases are gases, fundamentally.

No matter how much magic existed in this world, even it couldn’t perfectly control a basic physical law like ‘gas being carried away by the wind.’

Therefore, phosgene and chlorine were ill-suited to the North, where the wind blew so often.

Mustard gas, however, was different.

Many people were misled by the name ‘mustard gas,’ but this substance was essentially a sticky, oily liquid.

Once the liquid had clung to a person’s body or the ground, it wouldn’t simply blow away in the wind. The surface might evaporate... but that was the extent of it.

The wind couldn’t get rid of mustard gas completely. If anything, it concentrated the gas in low-lying areas like valleys and trenches. That was because mustard gas was heavier than air...
