The Bloody Sunday Inquiry is set to resume its work tomorrow.
It will be the first time since chairman Lord Saville ruled that British soldiers must go into the witness box.
The inquiry is set to sit four days a week until December 13th.
It will focus on the deaths of five of the 13 people shot dead when it resumes at the Guildhall in Derry after the summer break.
It is not known when Sinn Féin minister Mr Martin McGuinness will give evidence to the inquiry since admitting earlier this year that he was the second most senior IRA figure in the city on the day of the shootings.
The soldiers were told last month they must appear in Derry where 13 people were shot dead by the British Army in January 1972. Another man died later from his injuries.
The inquiry has cost an estimated £45 million sterling and has sat for 133 days so far.
