Retired Lt. Gen. Francis W. Farrell, 80, who served with an airborne division in the Pacific during World War II and who commanded an army in Germany at the time of his retirement in 1980, died at his home in Arlington Tuesday of a pulmonary embolism.

Gen. Farrell, who was born in Chicago, graduated from the U.S. Military Academy at West Point in 1920. He was commissioned in the infantry and later became an artillery officer. His assignments before World War II included a period as an instructor of West Point and another as director of gunnery at the Artillery School at Fort Sill, Okla. He also attended the Command and General Staff College.

During the war, he joined the 11th Airborne Division at the time it was activiated in 1942. He was the division's artillery commander during its campaigns in the Pacific. After the war, he was chief of staff of the 82nd Airborne.

During the Korean conflict, Gen. Farrell was named chief of the Military Advisory Group to the Republic of Korea and later served in Japan. When he returned to the United States in 1952, he was appointed the Army's deputy assistant chief of staff for operations.

Subsequent postings included command of the 82nd Airborne and special assistant to the Joint Chiefs of Staff for National Security Affairs. In 1957, he was sent to Germany as commanding general of the 5th Corps and in 1959 was named commander of the 7th Army. He retired from that post in 1960.

Gen. Farrell spent the next three years as director of the New York State Civil Defense Commission. He then established his residence in Arlington. From 1970 to 1972, he was president of the Army Distaff Foundation.

His military decorations included two Distinguished Service Medals, the Silver Star Medal, two Bronze Star Medals, two Air Medals and the Army Commendation Medal.
