Thirty years ago today the Sir Galahad was bombed by Argentinian jets.
Forty eight soldiers and seamen were killed in the attack including thirty two Welsh Guards.
The bombing happened while preparing to unload soldiers at Bluff Cove in the Falklands on the 8th June 1982.
For the army it was the biggest single loss of life since the Second World War and accounted for nearly a fifth of all British losses during the Falklands War.
In a recent ITV Wales programme many of the key commanders involved in the Falklands War spoke out about the vital decisions they made at the time.
After the attack, the Sir Galahad was sunk and later made an official war grave under the Protection of Military Remains Act.
One of those who died in the bombing was David Williams from Holyhead.
He was just 20 when he lost his life.
Today his family, friends and former comrades attended a service of remembrance in his home town.
