††††††††††† The convoy system was an idea to surround supply ships with battle ships to keep it safe.It went into use in the early months of 1917. It was used by Britan and America to get U.S. supplies and food to the Allies. The supply ships were beeing sunk by German U-boats trying to keep the materials from helping the Allies to fight back. The plan was to sink the U-boats when they came to the surface to shoot the ship. It cost much less to pay for the convoy than it did to replace the supply ships so they thought it would be good to send a convoy with them. After looking over the reports they noticed that it successfully reduced the ammount of ships thatís were sunk by the U-boats by a large ammount.
