Hello Navigator27 and welcome to the forum.
There was a link contained in the earlier thread about
ML 357 for
photographs of ML 357 and ML 351 posted on Pinterest, which are still available.
The campaign around the Dodecanese Islands consisted of multiple small-scale operations and patrols—with larger ones carried out at times—utilising a number of small raiding forces, including such elements as the Special Boat Squadron (SBS), the Long Range Desert Group (LRDG) and the Greek Sacred Squadron, as islands with small German garrisons were alternatively taken by Allied forces, and then retaken by the Germans. The SBS operated their own transport, known as the Levant Schooner Flotilla, supplemented at times by MTBs or MLs.
There is an interesting
overview of Aegean operations for the specific time period September–November 1943 produced by the Admiralty and originally published in the London Gazette, which provides an insight into the kinds of activities involved in the Aegean campaign. There are also a number of informative resources to be found under a search in Google for 'Levant Schooner Flotilla' and 'LRDG'.
I'll have a look through my own resources later for any specific information I may have on ML 357.
