The annual parade is held in memory of the thousands of Ulstermen who fought in one of the bloodiest battles of World War One – with around 2,000 killed and more than 3,000 wounded.
The parade set off from Templemore Avenue at 7.30pm, making its way along the Albertbridge, Ravenhill and Castlereagh roads, before returning to Templemore Avenue via the Upper Newtownards Road, Belmont Road, Holywood Road.
Here is a collection of pictures from the parade in east Belfast.
