Mary Seacole was a Jamaican nurse who risked her own life to treat the wounded in the Crimean War. As Mary was black, Florence Nightingale turned her away several times, so she set up her own 'British Hotel' and worked round the clock to nurse the soldiers. Often she would go out into the field to treat them too. A remarkable woman who is, at last, getting some recognition for her hard and dangerous work.

An official photo describing the kit of a British infantryman in 1939. Note that the gas mask ('respirator') and anti-chemical warfare cape are parts of the outfit, remnants of WW1 memories. In actual combat, and marching with full kit, the British infantryman would carry a pack known as a "valise" that contained more clothing and personal items. Officers wore the exact same uniform save for markings of their rank.
