Gen. Siegfried Westphal, 80, a German staff officer in World War II who was known as the "Paperwork Pedant" because of his meticulous planning, died July 2 at his home in Lower Saxony. The cause of death was not reported.

Born in Leipzig, Gen. Westphal began his military career in the Royal Prussian army at the age of 16.

Early in World War II, he spent a brief period as chief of staff to Gen. Erwin Rommel. In 1942, he was promoted to major general, becoming one of the youngest officers to hold that rank.

In 1943, he was sent to Italy as chief of staff to Field Marshal Albert Kesselring. During this period he became widely noted for developing a method of ground defense without air support.

In September 1944 he was named chief of staff to Field Marshal Gerd von Runstedt in France. He planned the German defense against the allied forces sweeping across western and northern Europe, including the Ardennes offense, of which the Battle of the Bulge was a major part. He was promoted to the rank of general of cavalry in 1945.

Released in 1948 from post-war imprisonment by the United States, Gen. Westphal began a successful career in the steel industry. He was director of the Rheinische Stahlwerke steel plant from 1960 to 1972.

A book entitled "Army in Fetters," which appeared in 1950, was translated into English and Spanish. He was editor-in-chief of "The Fate of North Africa," which appeared in 1954.

His efforts to reconcile former enemies won him the French Legion of Honor from President Charles de Gaulle.

He leaves a wife and two sons.
