Horse
Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30 years. Uncommonly, a few animals live into their 40s and, occasionally, beyond. The oldest verifiable record was "Old Billy", a 19th-century horse that lived to the age of 62. In modern times, Sugar Puff, who had been listed in "Guinness World Records" as the world's oldest living pony, died in 2007 at age 56.
Second Boer War
The number of horses killed in the war was at the time unprecedented in modern warfare. For example, in the Relief of Kimberley, French's cavalry rode 500 horses to their deaths in a single day. The wastage was particularly heavy among British forces for several reasons: overloading of horses with unnecessary equipment and saddlery, failure to rest and acclimatise horses after long sea voyages and, later in the war, poor management by inexperienced mounted troops and distant control by unsympathetic staffs. The average life expectancy of a British horse, from the time of its arrival in Port Elizabeth, was around six weeks.
