    In the summer of 1940, the Germans began to assemble an invasion fleet along the French coast.

Because much of the early research was performed at Columbia University in Manhattan, the Manhattan Project became the code name for research work that extended across the country.

  • U.S. convoy system

They were also accompanied by airplanes that used radar to spot U-boats on the ocean’s surface.

    Roosevelt responded to this threat by creating the Office of Price Administration (OPA). The OPA fought inflation by freezing prices on most goods. Congress also raised income tax rates and extended the tax to millions of people who had never paid it before. The higher taxes reduced consumer demand on scarce goods by leaving workers with less to spend.

    Bloody Anzio
    One of the hardest battles the Allies encountered in Europe was fought less than 40 miles from Rome.
