Today's work was quite busy, I'm afraid I can't write five chapters, sorry! Tomorrow I'll continue with five chapters!

"Aphro" fired smoke bombs at the German artillery positions.
The earliest smoke bombs were invented by a British officer named Motley in 1849, using silver nitrate and ferric oxide as the chemical agents. However, this smoke bomb was not effective, as the smoke it produced only made the enemy feel "there's smoke."
Shire used a formula improved by the Germans two years later, using potassium nitrate and sucrose as the chemical agents. Its smoke intensity was ten times that of the original smoke bomb, and it was cheaper and easier to obtain raw materials.
What Shire had to do was to fill these chemicals into rockets and get the pilots to fire them into the "danger zones."
