Lockheed Ventura, B-34, B-37, PV-1 and PV-2

The Lockheed Ventura was a medium bomber ordered for the RAF after the early success of the Lockheed Hudson, but was not as successful as the earlier aircraft, entering service too late to serve in the day bomber role it was designed to perform.
The Lockheed Model 37 was the USAAF designation given to 264 Ventura II medium bombers taken over from RAF orders after Pearl Harbor.
The Lockheed B-34 was the lend-lease designation given to the Lockheed Ventura, but of the 200 aircraft produced under this designation only 66 actually went to the RAF or Commonwealth airforces (as the Ventura IIA), while the remaining 124 were retained by the USAAF
The Lockheed B-37 was a medium bomber based on the Ventura, produced in very small numbers for the USAAF.
The Lockheed PV-1 was the designation given to the Ventura bomber in service with the US Navy.
The Lockheed PV-2 Harpoon was the final production version of the Ventura bomber, modified to make it a better maritime patrol aircraft.

No.22 Squadron began the Second World War as a torpedo bomber of Coastal Command, before moving to the Far East in March-April 1942. After spending the next two years flying anti-submarine patrols and convoy escort missions, it converted to the Beaufighter and spent 1945 as a ground attack squadron in Burma.
No.23 Squadron spent the entire Second World War serving as a night fighter squadron, first in a defensive role, but from December 1940 as an intruder squadron, from bases in Britain and on Malta and Sardinia.

The combat of Margalef of 23 April 1810 saw the defeat of a Spanish army attempting to help the besieged garrison of Lerida.
The combat of Tremendal of 23-24 November 1809 was a rare French success against one of the elusive bands of Spanish guerrillas.
The combat of Hostalrich of 7 November 1809 was a minor French victory in Catalonia, which played a significant part in their victory in the third siege of Gerona (24 May-11 December 1809).

The siege of Fuengirola of 13-15 October 1810 was a minor disaster suffered by the British in southern Spain during an ambitious attempt to help the hard-pressed guerrillas of Granada.
The third siege of Gerona of 24 May-11 December 1809 was one of the great epics of Spanish resistance during the Peninsular War, which despite ending in a French victory would act as a rallying call for Spanish resistance for the rest of the war.
