In 1919, the cavalry, artillery and draught horses that had served in the British Army in the Egypt and Palestine campaigns of
World War I had been sold in their many thousands to a life of continuous hard labour and a painful old age. Many had been requisitioned in England and had served in the
British Yeomanry. Some had seen active service on the
Western Front before being drafted as remounts to the
Near East. Strict
quarantine restrictions prevented the repatriation of the horses of the Australian and New Zealand Mounted Infantry. During World War I, horses cast from the veterinary hospitals had initially been sold to Egyptian dealers. British residents in Cairo had protested so forcefully that this practice had been stopped. After the Armistice, however, with 22,000 horses, mostly in Palestine and Sinai, requiring transport or disposal, the Remounts Directorate of the
War Office ordered the local sale of all animals of 12 years and under that were deemed up to some work. Those over 12 and the unsound were destroyed. The surviving horses had not had an easy war. They had carried often far too much weight – up to . They had experienced rationing, withstood piercing cold, dust clouds and exhaustion. Some may also have suffered both severe and light wounds. They had covered great distances, and some had endured a summer in the heat of the
Jordan Valley. By 1930, twelve years later, the war horses, many now of an advanced age, had been lost to view, toiling for the very poorest owners, or at night to avoid the police and Egyptian
S.P.C.A., or in the stone
quarries. Brooke had heard rumours from British residents who spoke of pitiful, emaciated creatures that they suspected were war horses. Their condition was said to be so bad that people could hardly bear to look at them. She was advised there could be two hundred. Weeks passed before she found the first, but eventually many more than two hundred were found. In the years from 1930 to 1934, she bought back 5,000 old army horses and mules. ==Campaign==
