UK forces’ final farewell to Iraq
By Jonathan Marcus BBC Diplomatic Correspondent
Some eight years of a campaign that deeply divided British society are coming to an end.
Now, the departure of a small Royal Navy training team on Sunday brings this operation finally to a close.
Some 179 British personnel have lost their lives in Iraq, 136 as a result of hostile action.
Many more were injured.
After the downfall of President Saddam Hussein, the UK’s mission became one of securing the mainly Shia south, which threatened to erupt into factional conflict.
It was a controversial mission.
But there were other questions too. Were the UK’s resources up to it? Were sufficient troops deployed and did they have the right equipment to do their job?
Many of the deficiencies of Britain’s Iraq operations have been discussed at length in evidence sessions to the Chilcot Inquiry into the origins and handling of the campaign. It is yet to complete its work.
