… On July 5, 1878, the Congress accepted the resolution proposed by the French plenipotentiary, 'inviting the Porte to come to an understanding with Greece for a rectification of the frontiers in Thessaly and Epiros, a rectification which may follow the valley of the Peneus upon the Eastern side, and that of the Thyamis (or Kalamas) upon the Western.' In other words, they assign to Hellas the whole of Thessaly and a large part of Epiros. Notwithstanding the abandonment of the island of Crete, this was some satisfaction for the wrongs which she had suffered at the delimitation of the Kingdom. … But the scheme suggested by the Congress and sanctioned by the Conference of Berlin on July 1, 1880, was not carried out. When Turkey found that she was not confronted by an Europe determined to be obeyed, she refused to submit. And then the Powers, whose main anxiety was peace at any price, instead of insisting upon her compliance, put upon Hellas all the pressure which they were able to exercise, to induce her to submit the question of the frontiers to a fresh arbitration. … Hellas had to yield, and on July 2, 1881, three years after the signing of the famous Protocol of Berlin, she signed the convention by which Turkey ceded to her the flat part of Thessaly and a small scrap of Epiros." _D.
