In Nicosia Beatrice gave birth to her first child, "a very elegant and wellformed son", as her brother-in-law Robert of Artois wrote home to his mother the Queen; however, the child lived only a few days. Beatrice stayed with her sister Margaret in Damietta, when they lost contact with the King and his army; here Beatrice gave birth to her second child, while her sister Margaret too gave birth. Later in 1250, they were reunited with the rest of the crusade at Acre, where the King's ransom was paid. Charles and Beatrice, along with several other nobles, left soon after and journeyed to the court of Emperor Frederick II, to ask him to send the King of France more men for his crusade. However, the Emperor, who had been excommunicated, needed his army to fight the Pope, and refused.
