Civil War battles re-enacted in Southern US states

The commemoration of the 150th anniversary of the US Civil War is triggering many re-enactments across America's Southern states.

In Charleston, a group of people have re-enacted the Battle of Bloody Bridge in which the Confederate army was able to fight back Union forces and claim a small victory towards the end of the war.

The BBC's Franz Strasser spoke to organisers and re-enactors about their motivation, if they mind playing Union forces every now and then, and if they think the war was portrayed accurately by the history books.
