Victory Bonds Will Help Stop This
This victory bond poster, published in English and French, depicts the 27 June 1918 sinking of the Canadian hospital ship HMHS Llandovery Castle by a German submarine.
The poster used a notorious incident at sea to reinforce support at home for the war effort and to promote the sale of victory bonds. While Germany's unrestricted submarine warfare had already sunk hundreds of civilian ships, the submarine U-86's sinking of the Llandovery Castle prompted outrage. After torpedoing the well-marked hospital ship, U-86 surfaced and attacked the lifeboats, leaving only 24 survivors from a crew of 258. Among the dead were 14 Canadian nursing sisters.
