Input: Question: How old was the king when he awarded Mairi and Knocker the Order of Léopold II, Knights Cross? Passage:Chisholm and Knocker soon came to the conclusion that they could save more lives by treating the wounded directly on the front lines. In November, they decided to leave the corps and set up their own dressing station five miles east in a town named Pervyse, north of Ypres, just one hundred yards from the trenches. Here, in a vacant cellar which they named "Poste de Secours Anglais" ("British First Aid Post"), the two would spend the next three and a half years tending to the wounded. No longer affiliated with the Belgian Red Cross, they began acting completely as free agents and had to support their work by raising their own funds. Through sheer perseverance Knocker was able to arrange for the two of them to be officially seconded to the Belgian garrison stationed there. In January 1915, they were both decorated by King Albert I of Belgium with the Order of Léopold II, Knights Cross (with palm) for their courageous work on the front lines. They were also awarded the British Military Medal and both made Officers of the Most Venerable Order of St. John of Jerusalem. Chisholm was also decorated with the Queen Elisabeth Medal of Belgium and the British campaign medals, including the 1914 Star. The two became instant celebrities earning the distinction of being among the most photographed women of the war.
