Battle of Okinawa

In the past, a big war between Japan and the U.S was held in Okinawa.
When I was little, I asked my grandmother about the Battle of Okinawa, and her experiences.
My grandmother was about 21 years old then, which is pretty much like our age.
She was in Ishigaki island and lived close to her friends' houses.
When she heard that the Americans coming to their island, she and her friends hide in the forests. While they were in the forest, one of her friend was shot on her shoulder, and died.
The biggest enemy was not only the bombs, but also mosquitoes. Malaria was widely spread to people who live in forests. Many of them died because of it. My grandmother couldn't sleep much and had to take care of her friends who suffered from Malaria.
