The Division Sardinia was formed on May 12, 1943, in Sardinia from the staff of the Sturmbrigade XI (11th Assault Brigade).
It became division strength just as the Army Group Africa was surrendering in Tunisia.
The original reason for the creation of the division was due to its exposure to the allies after the "official" end of Operation Torch.
Because the invasion of Sardinia never happened the division was "de-mobilized" and helped the re-incarnation of the 90th Panzergrenadier Division in 1943.
