In 1912, the league launched The Blue Cross Fund to care for horses during the Balkan War. On the outbreak of the First World War in 1914, it was quickly reopened again. By the armistice in 1918, the Blue Cross Fund had raised nearly £170,000 – the equivalent of almost £6.5 million today – to care for the animals of conflict. Over 50,000 horses were treated in Blue Cross hospitals in France, and the charity had sent vital veterinary supplies to 3,500 units of the British Army.
