What happened May 1937 AD

April and May saw the May Days, infighting among Republican groups in Catalonia. The dispute was between an ultimately victorious government—Communist forces and the anarchist CNT. The disturbance pleased Nationalist command, but little was done to exploit Republican divisions. After the fall of Guernica, the Republican government began to fight back with increasing effectiveness. In July, it made a move to recapture Segovia, forcing Franco to delay his advance on the Bilbao front, but for only two weeks. A similar Republican attack, the Huesca Offensive, failed similarly.

Letters Patent dated 27 May 1937 re-conferred the "title, style, or attribute of Royal Highness" upon the Duke, but specifically stated that "his wife and descendants, if any, shall not hold said title or attribute".
