§ Of the Return of the Noldor The Silmarillion

But Fingolfin, being of other temper than Fëanor, and wary of the wiles of Morgoth, withdrew from Dor Daedeloth and turned back towards Mithrim, for he had heard tidings that there he should find the sons of Fëanor, and he desired also to have the shield of the Mountains of Shadow while his people rested and grew strong; for he had seen the strength of Angband, and thought not that it would fall to the sound of trumpets only. Therefore coming at length to Hithlum he made his first camp and dwelling by the northern shores of Lake Mithrim. No love was there in the hearts of those that followed Fingolfin for the House of Fëanor, for the agony of those that endured the crossing of the Ice had been great, and Fingolfin held the sons the accomplices of their father. Then there was peril of strife between the hosts; but grievous as were their losses upon the road, the people of Fingolfin and of Finrod son of Finarfin were still more numerous than the followers of Fëanor, and these now withdrew before them, and removed their dwelling to the southern shore; and the lake lay between them. Many of Fëanor's people indeed repented of the burning at Losgar, and were filled with amazement at the valour that had brought the friends whom they had abandoned over the Ice of the North; and they would have welcomed them, but they dared not, for shame.
