Hospital ships were generally painted white with a green line running along the sides & red crosses on sides & occaisionally funnels.
Between 1915 & 1919 hospital ships accounted for 494 visits to Malta.

I started off trying to identify a couple of photos & got carried away.. This is the result.

This is a scan of a postcard in circulation around 1914 showing a hospital ship berthed near Lascaris Bastion.
I have seen one of these postcards dated October 1914 written in French with no stamp which would suggest it being written by a soldier/serviceman.

I had some old photos sent of hospital ships which I started to try & identify. During this research I started to get interested in Malta's work during WWI.
The ships below either visited Malta with wounded from Gallipoli & Salonika or were sunk near by.
During the Crimean War & WW1 Malta was used as a place to evacuate wounded. From Gallipoli 2500 officers & 55,400 troops were taken to Malta.
The photos above came to me without any information & were probably pre-WWII.
Photographs are hard to find but e-Bay generally has some available.
Some 50,000 casualties were transported to Malta, Gibraltar & the UK.
In Malta some 20,040 beds were eventually available. Some 2,550 officers and 55,400 other ranks treated the wounded.

List of Hospital Ships known to have been in the Mediterranean during WWI
Three types of hospital ships were used -
The large liners Aquetania, Mauretania & Brittanic were used as hopital ships towards the end of the war.
Properly painted white ships with large red crosses & sometimes green bands along the sides.
So called 'Black Ships' which were normal coloured or non white painted ships also used to carry troops. Used mainly at night.
These were 'fair game' for U boats as they were not painted as hospital ships.

It was common practice to send troops to Gallipoli in normal ships & return them to various ports as hospital ships.

Destinations wounded were taken to.
Lemnos, Imbros, Egypt, Malta, Salonika, Alexandria, Gibraltar, UK.

Aquitania	Large converted passenger liner. This was the largest of the liners used with a capacity of some 4,182 beds. Due to her size this ship would carry troops directly to England.

Maine (3)	Photo courtesy of Denis Darmanin whose father served on the ship. Photo courtesy of Cheryl Beasley - We think this is Maine. Originally named SS Panama when launched in 1902. Although not converted to a hospital ship until 1920 (conversion completed 1922) I am listing the ship here. This ship was based in Malta for a time & used to berth off Senglea Point. On the 28th February 1928 a storm hit Malta & she broke free off her mooring lines & was grounded. The ship was still in action in WWII where she was based in Alexandria treating more than 13,000 patients. On the 6th September 1941 she was narrowly missed in a bombing raid which caused some damage. On the 21st February she was sold for breaking up.
