Back in his home in Geneva, he decided to write a book entitled "A Memory of Solferino" which he published using his own money in 1862. He sent copies of the book to leading political and military figures throughout Europe, and people he thought could help him make a change. In addition to penning a vivid description of his experiences in Solferino in 1859, he explicitly advocated the formation of national voluntary relief organizations to help nurse wounded soldiers in the case of war, an idea that was inspired by Christian teaching regarding social responsibility, as well as his experience after the battlefield of Solferino. He called for the development of an international treaty to guarantee the protection of medics and field hospitals for soldiers wounded on the battlefield.
