Visiting the beautiful Outer Hebrides on holiday I was struck by what looked like war graves in two burial grounds. These turned out to be the graves of men "Known unto God", WW II merchant seamen whose bodies had been washed ashore without any identification.I was interested to know more about these islands at war and this book tells the story of their contribution to defending the convoys and defeating the U boats. It is a story of bravery and humour from what seems like another age. I was prepare for tales of thatched crofts but not of barefoot school children. The book is well illustrated with many photos, quite a number of which must have been taken against regulations.
