Colophon - Thanks to...

During the building of this web-site I received help and support from many different people and organisations. Firstly, thanks to my family for their support and for listening to so many details about The Defence Line. Many others also helped and I want to thank them for it. See the Dutch version for the full list of names of people and organisations.

Many thanks go to Siobhan Hearne (Ireland) for reviewing and correcting most of the English texts.
