A documentary marking a century since the greatest sea tragedy ever to befall the west coast of Scotland is to be shown on national TV next week.

The Iolaire was carrying sailors who had fought in the First World War back to the Isle of Lewis in the Outer Hebrides on Hogmany, 1918.

She departed Kyle of Lochalsh, but at 2.30am on New Year’s Day, she hit the infamous rocks known as the Beasts of Holm, and sank, just a mile away from the safety of Stornoway Harbour. At least 201 of the 283 men onboard died.

Incredibly, this tragedy remains largely unknown.

Through the testimonies of the islanders, all aspects of this deeply moving story are featured in this documentary, including tales of extraordinary bravery and foresight.

A service of remembrance was held on 1 January this year, with Prince Charles and First Minister Nicola Sturgeon on attendance.

The MSP for the Western Isles, Dr Alasdair Allan raised the issue of the site becoming a war grave at First Minister’s Question Time later that month. The First Minister confirmed that she was supportive of the move.

This documentary, In Sight Of Home: The Iolaire, was first shown on BBC Two Scotland.

In Sight Of Home: The Iolaire will be shown on Tuesday 30 April, on BBC Four, from 9–10pm.
