In putting together this site I have received help and assistance from many people, from the UK, Canada, Australia, Iceland, Sweden, the United States and Germany.

Special thanks are due to Peter and Margaret Tingey in Australia. Peter was serving as an apprentice on the Canonesa when she was torpedoed and his descriptions of the events of that night, and his memories of my grandfather, have been fascinating and invaluable.

I am also extremely grateful for the information and photographs provided by George Barrat, whose father was also on the Canonesa when she was hit, Alan Shard who was on the Putney Hill during the attack, Dennis H. Johnzon who served on a number of Houlder Brothers ships, including on the Canonesa's penultimate voyage, and John B. Hill, another expert on Houlders.

Very helpful information has also been provided by William C. Dawson (of the U-Boat Association), R.S. Thomas (who was serving on the Pacific Grove, the Furness Withy ship immediately behind the Canonesa in Convoy HX72), Kyle Schepke (distant relative of Joachim Schepke), Chas Walker, Fred Hortop, Maureen Venzi, Wade Manning, Alan O Watkins, Colin Knight, G.V. Monk, Peter Skelton, Johann Ingi Palsson, Arnold Crossley, Cliff McMullen and Des Steel. Dave Carter kindly scanned a number of images for me (check out Dave's fine stock car racing site rolling START). I thank them and anybody else I may have inadvertently forgotten!

Carsten Corleis, who runs an excellent web-site in German called U-Boot - Die Geschichte der Deutschen Weltkrieg-II U-Boote, provided me with the German translation of my site description. Michael Sjödin's Unterseebootwaffe, based in Sweden, has also been a useful resource.

Useful information was sourced from U-boat net run by Gudmundur Helgason of Iceland. I am particularly grateful to him, and his colleagues Juergen Schlemm and Dr Clemens Brechtelsbauer, for permission to reproduce a number of photographs and illustrations from this site and for providing a translation of U-100's war diary. Look in particular at the following pages for information directly relevant to Canonesa, Convoy HX72 and U-100.
