During civil disobedience movement she became the leader of the women wing of the congress in Delhi and led the movement. She organised the breaking of the Salt Law in Delhi where she and a group of volunteers manufactured and distributed packets of illegal salt to people gathered there. She was arrested by the police and was sentenced to two years imprisonment in 1932. While she was imprisoned in the jail she contracted pleurisy and tuberculosis. While at jail, despite being very ill, she refused to give a bond of good behaviour and assurance that she would desist from political activity, that could have secured her release and hope for treatment. She died in 1945 at the age of 39 from tuberculosis. Writings
Jailed women political freedom fighters composed poems and nationalist tracts, which were smuggled out and published. One of the pieces written by Satyavati Devi, titled ‘Bahin Satyavati Ka Jail Sandesh’ (Sister Satyavati's prison message) goes as follows:
This is a message from your jailed sister
Sister Satyavati appeals to you
Do not slacken from your work
Jump, if required, into the burning flames
The sacred battle should be full of strength
Once you have stepped forward, never retreat
Die before the men in the battlefield
Do not fear bullets or sticks
Put your head forward before the men
Once lit, the fire should never go out
I have full faith now
Because the women have prepared themselves  

This and other writings and prison songs seemed to be aimed at motivating and mobilising women to enter India's Independence movement. Recognition
Although she is believed to be an unsung hero of India's freedom struggle, Satyawati College (Delhi University) established by the government of Delhi in 1972 is named after her.
