During the first US Civil War many would have a bedroll worn like a bandoleer. Unrolled it was everything they owned at that time. Items such as coats, extra clothing, nice boots and etc were left at home. When needed
letters were sent home, via members going to that area, to have the items shipped to the member.
I started reading letters to home from the Civil War. On both sides the entries were the same:
That members concern about his job (role in the military.)
That members concern about his/her health.
That members concern about the health and safety of his/her family members.

Growing up and then as an adult I had always been concerned about helping others. I have now come
to realize I am not worth anything if I am dead or severally injured.
Like the airlines keep telling us: when in an emergency place the mask on yourself first!
