Please examine this sentence:

Answer

I personally like to start a sentence with..

In order to quell/quench Baghdad uprisings,  they unleashed poison gas on Baghdad's people.  (if you are talking about the 1991 Baghdad uprisings)

But you can also start with To if you like.

I dont think carpet drop poison gas is an appropriate term;  I have only heard of carpet bombing .
The Baghdad uprising? was there a particular uprising, if so , yes, you can use the Baghdad uprising.

Answer

You must say "the Baghdad uprising".
You cannot say "[no article] whole of Baghdad".

Alternatively, you can say: 
"To quench Baghdad uprisings..."
"... gas on all of Baghdad."

Poison shouldn't be capitalized.
