Caine, Thomas J., born 1891, died 1918, 32 Service Co. S.C.U.S.A. World War.
According to the burial registers in Winchester, England, he died in a Southampton Military Hospital in 1918 aged 26 years. He was buried in Magdalen Hill Cemetery on 9th October 1918 with full military honours. His remains were exhumed on 24th March 1920 by order of the Home Office who worked in conjunction with the families of the deceased. The families were given the option of having their loved ones re-interred in a US Military Cemetery in the UK or repatriation to the US.

Many of these servicemen and women contracted the influenza either in the Training camps in the US or the transport ships bringing them to the South Of England. There were vast military camps in this area preparing to send the troops to France. Sadly many of those with the flu developed Pneumonia which they succumbed to.
