Over one thousand (1,039) men from Berkeley County participated in World War I. Of these, forty-one were killed, and twenty-one were wounded in battle. A monument to those who fell in battle was erected in Martinsburg in 1925.

During World War II, the Newton D. Baker Hospital in Martinsburg treated thousands of soldiers wounded in the war. In 1946 this military hospital became a part of the [[Veterans Administration]] (VA). The VA Medical Center in Martinsburg still provides care to United States veterans.

Due to restructuring beginning in the late 1940s and continuing through the 1970s, many of the mills and factories operating in Martinsburg shut down and went out of business, dealing a major blow to the local economy. Jobs were moved to the Deep South and later offshore.
