Trasimene Line

The Trasimene Line (so-named for Lake Trasimene, the site of a major battle of the Second Punic War in 217 BCE) was a German defensive line during the Italian Campaign of World War II. It was sometimes known as the Albert Line. The German Commander-in-Chief (C-in-C), Generalfeldmarschall Albert Kesselring, used the line to delay the Allied northward advance in Italy in mid June 1944 to buy time to withdraw troops to the Gothic Line and finalise the preparation of its defenses.

After the Allied capture of the Italian capital of Rome on 4 June 1944 following the successful breakthrough at Monte Cassino and Anzio during Operation Diadem in May 1944, the German 14th and 10th Armies fell back: the 14th along the Tyrrhenian front and the 10th through central Italy and the Adriatic coast. There was a huge gap between the armies and with the Allies advancing some 10 km per day, the flanks of both armies were exposed and encirclement was threatened.

Two days after Rome fell, General Sir Harold R. L. G. Alexander, Commander-in-Chief (C-in-C) of the Allied Armies in Italy (AAI), received orders from his superior, General Sir Henry Maitland Wilson, the Allied Supreme Commander in the Mediterranean Theater of Operations (MTO), to push the retreating German Army 170 miles north to a line running from Pisa to Rimini (i.e. the Gothic Line) as quickly as possible to prevent the establishment of any sort of coherent enemy defense in central Italy.
