The Allies (Triple Entente) stop US ships and confiscate goods purchased by the
Central Powers (Triple Alliance), including
food and fertilizers for crops. Famine
plagues Germany by 1917. 750,000 Germans
starve to death as a result of the blockade.
The Allies ignore formal complaints by the
US, but increase their orders for war
supplies from American manufacturers.
