Spanish Flu, (FIRST World war)

The Spanish Flu ended the first world war, not the second world war. Spanish flu was highly contagious. Young and old healthy or not would get symptoms and die as quickly as 6 hours from the initial symptoms. This makes COVID-19 seem a bit weak. The second world war was ended by two main invasion forces. The combined D-Day beach invasion that included forces from the USA broke through enemy lines into Europe. A separate large invasion force was formed and left from Russia that struck straight into the heart of Nazi Germany. This was after the Nazi attempt to take Russia. (I think someone in the high command in Germany must have been numerically dyslexic – dyscalculia.)
