I didn’t see one.

According to the Scottish War Memorials Project there isn’t one.

I suppose it is faintly possible that since the young men would have been employed in the fishing industry (a reserved occupation) none of them actually went to war. Would that have been all the young men though?

The link above says there is a memorial to the dead of Morar, which is three miles south of Mallaig. Morar is close to Loch Morar, the deepest freshwater loch in the British Isles, and supposedly home to Morag, the loch’s equivalent of Nessie, the Loch Ness Monster.
