Describe the two main steps of the French Revolution.How would I describe the scene of the revolution?

The French Revolution began in June 1789 with the Third
Estate's members convening in what has come to be known as The Tennis
Court Oath, a pledge signed by them that would effect a new
constitution.  This oath, which was a revolutionary act, was an assertion that political
power derived from the people and not from the monarchy.  The oath signified the first
time that French citizens were in opposition to the
monarchy.

The second event of the burgeoning revolution
is the march to and attack on the Bastille in July,
14, 1789.  Since the old prison held only seven prisoners [Dr. Manette is one], the
attack was more figurative than literal.  It signified the end of royal authority and
most prisoners in the Bastille were political ones.  After this storming of the
Bastille, the Declaration of the Rights of Man was written.  After some conflict between
liberal assemblies and a conservative monarchy intent, a republic was proclaimed in
1792. 

Monsieur and Madame DeFarge participate in the march
upon the Bastille. In Book the Second, Chapter 21, Madame DeFarge is
in

...the
howling universe of passion and contention that seemed to
encompass....

When an old
grim officer falls dead, Madame DeFarge  becomes "suddenly animated" and, placing her
foot upon his neck, and with her"cruel knife--long ready--hewed off his
head":

Saint
Antoine's blood was up, and the blood of tyranny and domination by the iron hand was
down--down on the steps of the Hotel de
Ville....
