Archer 17-pdr self-propelled gun near Nutterden, 9 February 1945.(Germany,Nordrhein-Westfalen)

You always hear about the vulnerability of open top SP guns, but they were always meant to be more mobile versions of AT weapons already in use, that is to say, to be driven to a static position then fired. Something strikingly different to the doctrine of an assault gun.

The No 211 moved from Middle East to Greece middle November 1940 as part of the British Air Forces contingent sent to support the Greeks after the Italian attack. On 17 November 1940 the No 211 is based at Menidi, Tatoi, Athens with a detachment at Paramythia. Victor Sierra

British bombs over Valona

Mary of Exeter, heroic British carrier pidgeon, awarded the Dicken Medal for her war service, November 1945. Mary survived a number of scrapes in her message-carrying duties, including injury believed to have been inflicted by German anti-carrier pidgeon hawks over the Pas-de-Calais. Strange, but true. JR.
