Explain the two major ironies of de gaulles professional life

During World War I, de Gaulle earned distinction on the battlefield. He was wounded twice and received a medal for his acts of bravery. Promoted to captain, he fought in one of the war's bloodiest confrontations, the Battle of Verdun in 1916. During the fight, he was wounded and subsequently arrested.  After several failed escape attempts, de Gaulle was released at the end of the war. A fervent nationalist de Gaulle did not accept France's surrender to Germany during Pétain's rule. He fled to England, where he led the Free France movement, with the support of British Prime Minister Winston Churchill.  From London, de Gaulle transmitted messages of support to his countrymen: "Speaking in full knowledge of the facts, I ask you to believe me when I say that the cause of France is not lost," he said. He also organized soldiers from the French colonies to fight alongside the Allied troops.   As a French leader, de Gaulle sometimes irritated other leaders allied with his requests and his arrogance. US President Franklin D. Roosevelt, for example, could not stand him.  Indeed, at the end of the war,  Gaulle was intentionally excluded from the Yalta Conference while Germany negotiated his surrender.
