The Battle of Tuiteam Tarbhach (Scottish Gaelic: "plentiful slaughter";[1] also known as Tuttim–Tarwach, Tuttim–Turwigh, Tuttim–Tarwigh or Tutim Tarvach) was a Scottish clan battle in which the Mackays wiped out raiders from the Clan MacLeod of Lewis who were returning from an attack on Mackay land in Strathnaver.

Failing to come to an amicable agreement, Malcolm ravaged Mackay lands in Strathnaver, and the Sutherland district of Brae-Chat (Breachat),[1] around Lairg at the south end of Loch Shin.

The river is the traditional boundary between Sutherland to the north and Ross to the south, and is a major transport artery linking the East Coast to the MacLeod territory of Assynt in the west.

The Mackays and Sutherland men caught up with the MacLeods as they were crossing the Tutim Burn, laden down by booty and stolen cattle.
