Bit of a late reply, but a reply none the less :)

Well strictly speaking, it's more of a question. Since Lusitania and her sister where built with government subsidies, and were built with military service in mind. Why didn't they think to amour the vessels? Yes I know, expensive, but after all, they where built with this in mind, even the plans have mounts for 6'' guns etc. Rather pointless for the British to spend all that money in something that is, from a military point of view, worthless. But, what I am most interested in is why they used Mauretania for service, but kept Lusitania in public service (all be it, once a month trips). Thanks a lot ;)
