The intention was to prevent the loss of life by make it easier for soldiers to perform emergency first aid. The bandages could be used as tourniquets, slings, and to secure splints to broken limbs.
The St. John Ambulance Association was founded in 1877 in England, and was the first company to produce the bandages. Starting in 1890, triangular bandages were included in all first aid kits by the American company Johnson and Johnson, and they were also later produced by Bauer & Black in Chicago. The bandages had illustrations showing anywhere from twenty to forty different ways that it can be worn, and the pictures could be understood easily by everyone.
