The Marines had a guy in the 30s who knew the Japs were fortifying their mandated islands and he did some recon and paid w/his life.
His name was “Pete” Ellis. He knew what was coming on the horizon.
Guadalcanal, Tarawa, Biak, Bouganville, Pelileu, Saipan, Iwo Jima and Okinawa.
The Marines proved that sea-borne invasion can be accomplished!
God bless The Corps!
