The Spa circuit was 'by-passed' by the Bulge fighting ; it is rumoured but unproven that some recce elements of Kampfgruppe Peiper may have passed along the southern leg of the old cicuit ( ie through the Masta Kink ).

But Stavelot was heavily involved in the fighting between US forces and KG Peiper - for full accounts see Michael Reynolds' book 'The Devils Adjutant' or Pallud's 'Battle of the Bulge - Then & Now'.
