Hello everyone and welcome back to our weapons and the first world war series. For years, the military had been hampered with the problems gun powder produced. In particularly, the fact that the was more often than not no visibility due to a thick cloud of smoke on the battlefield. 

In 1886, Paul Vielle invented a substance known as Poudre B. When fired, this substance formed little, if any smoke. It was also deemed to be more powerful than gun powder and so whilst it was the French that first used it, other countries soon followed suit. 

Poudre B meant that visibility was slightly better on the first world war battlefields than that of previous battles when using standard gun powder. It also shaped the way our weapons our designed and made today and certainly helped us to go on to win the second world war.
