GIULIO CESARE


GIULIO CESARE


The Cesare on the afternoon of July 9,1940, returning to base after the Battle of Point Stilo.


The Cesare with Veneto in the background, anchored in Naples in January 1942. The photo was taken at the close of an air raid during which Cesare was damaged by near miss.


The effect of the 15-inch hit by Warspite on Cesare, during the Battle of Point Stilo (known by the British as the Action off Calabria) a few minutes after hit.


July 9, 1940, 3:59 p.m. The Cesare being hit amidships by the British battleship Warspite.


The Cesare at sea, on Dec. 17,1941.
Note the ships upperworks are camouflaged, the hull is not. Painting of the ship was interrupted by orders to sail, indicative of the urgency ascribed to escorting the mid-December convoy to North Africa.


The Cesarein Tarano, Nov. 1948, re-entering the port following engine tests, during her refit, prior to being delivered to the USSR as mandated by the peace treaty.


Giulio Cesare Feb. 1949, Vlore, Albania, close before russian handover.
