Two Wicklow town men were among the crew of the Irish Naval Service vessel the LE Samuel Beckett which returned to base at Haulbowline in Co Cork over the weekend.
The ship had been involved in Operation Pontus, a humanitarian search and rescue mission on the Mediterranean, co-ordinated by Italian authorities.
The mission was featured in the RTE documentary 'The Crossing' which aired on Monday, December 12.
Wicklowman Seán Doyle was a medic on the ship.
Sean was a member of the Wicklow RNLI crew before joining the Naval service. He attended De La Salle Wicklow and played under age rugby with Wicklow RFC.
Also on board for the mission was Ordinary Seaman Myles Murray, who is in the service just over a year.
Myles also played under age rugby with Wicklow RFC as well as soccer with Wicklow Rovers. He is a former pupil of Wicklow Montessori School, De la Salle Wicklow, and Choláiste Cill Mhantáin.
Over the past three-and-a-half months, the Irish Naval Service has published bulletins on their Facebook page detailing the thousands of migrants and refugees which they have rescued from the sea.
