Mr. Duffy was shot dead by the SAS as he went to check on an arms dump in a house in Maureen Avenue in November 1978.

The march, which was organised by the 32 County Sovereignty Movement and the Duffy family, began at the Brandywell grotto and made its way to the Republican Plot in the City Cemetery.

A number of PSNI landrovers accompanied the parade and marchers were told they were taking part in an illegal parade before it set off.

In the cemetery, wreaths were laid on behalf of the 32 County Sovereignty Movement (32CSM), the Duffy family, and Oglaigh na h'Éireann. The main oration was given by Marian Price, the national secretary of the 32CSM, who told the crowd that the republican movement is being rebuilt.

"Republicanism is alive and well and it's the only ideology and plan for Ireland that hasn't been tried and it was time that it was put into action. We are beginning to rebuild the republican movement and from here it's onwards and upwards," she said.
