A combination of factors, but mainly intelligence allowing the UK to focus assets (air craft, submarines, occasional surface action) against the shipping. Again Malta's influence is intelligence and restricting timing/routes because of the threat. Coastal shipping used small ports, which are not well defended so vulnerable to attack.Interesting. How did this happen? Attacks by air and mining ops?
This discussion was called "The Great N.A. Logistical Debate". It cover a lot of ground over 3+ years. I have provide a few links below to various parts of the discussion. When I joined in in 2001, there had already been some previous discussions, so going back further in the thread might yield some more info.Also, do you have a link to that discussion?
If you wish, use the extended search tool and use my name (Leser) to find my posts with the data I presented. Start date needed to be 3 Jan 2001. The search results screen give the content, so an easy way to scan through the posts. You will need to go at least through 2004, but I didn't check to see when it informally ended. A lot of dross to work through to find the good stuff.
Note this discussion got quite argumentative and heated. Part of that was my fault, but much was due to others. BTWs, a typical online debate/argument.
Here is a link to the search engine. Use Leser start date 3 Jan 2001, end date sometime in 2005.
