This is all out the period, we are aware. After a recent a period of time in Malta we could find no readily accessible database of military sites for World War II in Malta. This is unlike the UK and Hong Kong, see details below, where detailed databases have been made available.
As a side project therefore, we plotted the Pillboxes and Defence Points we could locate and have produced this basic database. If you identify any errors or omissions, please advise us on email@example.com, so that we can make suitable adjustments, I am sure there is lots of stuff left off.
In the UK we have The Defence of Britain Project (Council for British Archaeology (2006) Defence of Britain Archive [data-set]. York: Archaeology Data Service [distributor] https://doi.org/10.5284/1000327) extensively covers most of the World War 2 features in the United Kingdom We have a variation of this on https://edob.mattaldred.com/map/. The Pillbox Study Group offers downloads through their website, see http://www.pillbox-study-group.org.uk/links/downloads/.
In Hong Kong there is a similar and far more modern database covering the fall of Hong Kong in 1941. See their home web site at https://digital.lib.hkbu.edu.hk/1941hkbattle/en/about.php.
The best read in respect of this subject remains the book by Steven Spiteri, (1996). British military Architecture in Malta. Second hand copies do appear for sale sporadically.
The Pillboxes in Malta were organised in successive Stop Lines, similar to those in the United Kingdom. The posts were each given a prefix depending on their perceived role. In basic terms the Beach Posts were on the shore, the Support Posts at key features slightly further inland and the Reserve Posts to provide support to the more advanced positions.
BEACH DEFENCE POST – designated by an abbreviation of the area and a number, for example MB1 was Mellieha Bay Number 1 Beach Post. The Beach Defence Posts usually has a Lyon Light emplacement close by for illumination.
SUPPORT POST– these were designated with the prefix of “L”
RESERVE POST – these were designated with the prefix of “R”
GUN POSTS has the prefix “GP”
The British Army had built semi-permanent field defences in the North of Malta from about 1903 onwards, but it was not until after 1935 that they moved towards pillbox structures. This development was similar to that seen in Hong Kong, although for different reasons. The Shing Mun Redoubt and Gin Drinkers Line in Hong Kong were a product of British military thinking prior to 1939. Fort Campbell in Malta was also built at this time, and these coastal defences provide interesting comparisons of military architecture at this time.
The building of pillboxes (Defence Posts) came in two distinct phases. The initial buildings were well built and finished. As the War developed, Malta came under siege and resources became scare. Set designs were adopted for the Defence Posts, thus allowing for standardization and a quicker build time.
Emergency measures were taken during 1940 to 1943 and a number of ad hoc structures supplemented the prescribed Defence Posts. The included the use of existing structures such as houses and factory buildings, which were adapted.
