The **Spring 1945 offensive in Italy** was given the code name **Operation Grapeshot**. It was the Allied attack by Fifth United States Army and British 8th Army into the Lombardy Plain. It started on 6 April 1945 and ended on 2 May with the surrender of German forces in Italy.

Background
----------

The Allies had done their previous major attack on the Gothic Line in August 1944. The British 8th Army attacked up the coast of the Adriatic Sea. The U.S. 5th Army attacked through the central Apennine Mountains.

They managed to break through the Gothic Line defences. But they failed to get into the Lombardy Plains before the winter weather stopped them. 
They had a hard time in the cold winter weather. They planned to attack again in the spring.

### Command changes

Harold Alexander was promoted to Field Marshal. He was made the Allied Supreme Commander Mediterranean on 12 December.

On 23 March, Albert Kesselring was appointed Commander-in-Chief Army Group West.

### Orders of battle

### Plan of attack

Allied Spring Offensive April 1945: Note that 21 ID NZ is actually New Zealand 2nd Infantry Division
Clark made his plan on 18 March. He wanted destroy the maximum number of enemy forces, cross the Po and capture Verona.

The Eighth Army was to go north west to capture Ferrara and Bondeno. The U.S. Fifth Army was to go past Bologna to surround German forces south of the Po. The Fifth Army was to go west towards Ostiglia. Next, the Allies would capture bridge across the Po and go north.

The Fifth Army plan (Operation *Craftsman*) aimed to pull German reserves away from Route 65. II Corps would then attack.
