Every year since 1973 the Exeter Flotilla has held a Trafalgar Service in Exeter Cathedral to commemorate Lord Nelson's great victory in 1805.
This year, on Sunday 19 October, the White Ensign will once again fly over the cathedral.
The service starts at 11.30am and will be attended by the Lord Lieutenant of Devon, the High Sheriff of Devon, the Lord Mayor of Exeter, and Senior Royal Navy and Royal Marine officers.
The congregation will include contingents from HMS Drake, HMS Raleigh, HMS Vivid, Britannia Royal Naval College, Dartmouth, and Sea Cadets from Devon units.
To start the service, the bell of the last HMS Exeter will sound seven bells. A cross made from the mast of the fourth HMS Exeter will be on the altar. The Trafalgar Roll, listing the 1,115 Men of Devon who fought with Admiral Nelson at Trafalgar will be on display.
Former Royal Navy chaplain, the Reverend John Morris will give the address, and lessons will be read by Major General David Hook and Rear Admiral Ben Key.
Lord Nelson's prayer will be read by the chairman of the Exeter Flotilla, Commander Rory Jackson RN.
Music will be provided by the Band of Her Majesty's Royal Marines, Commando Training Centre, Lympstone.
All are welcome to attend the service.
