"The earliest new-year batch of US-supplied wooden steamships, led by the S.S. Accomac, arrived in British ports. These January deliveries served as a show of strength and resolve, as Anglo-American forces continued to fight the Great War without France.
It was a long and winding road from the German Spring Offensive of 1918, which had captured Paris and convinced France to stand down her exhausted forces and accept a position of strict neutrality for the remainder of the war.

The next step was to face the fact that USA steel industry simply lacked the capacity to build both the navy ships, mostly destroyers, refit the 431 already seized cargo ships, and construct the additional 1,000 ships planned for the war cargo fleet expansion program…"
