Hey ya Leprechaun,The term Hun is used a lot just to describe a bloodthirsty warring people or person, so yes in the view of the Irish republicans the English were Huns. Also the fact that the English are Anglo-Saxons, Anglelandt and Saxony being part of Germany and Denmark. But the phrase Britains sons is one I have found more common and it is more appropriate I think.
Sud el Bar was a battle area in WWI, but having just done a quick check of my history books I can't find a good reference to it. It is in the Middle East and I'm sure that Australia was involved as that is why I would have a reference in my mind. I think it was in Egypt, maybe the same time and area as the Beersheba charge. Don't quote me.
