Thank you very much.
One needs to copy the full URL:
http://infogestnet.dyndns.info/infogestnet2007/registo.aspx?id=130499>>>|http%3a%2f%2finfogestnet.exercito.pt%2finfogestnet-pesquisa%2finfogestnet-pesquisa.asmx|&grupoarquivo=43&arquivo=AHM+-+Da+Guerra+Peninsular+à+Regeneração&texto=Infantaria+20&tipo=registo
and paste it to one's browser. The HyperLink has picked up your first name 'Jorge' and therefore does not work.
Also, for those unfortunate souls that do not read Portuguese, one needs to 'Click' on 'Miniaturas' at the bottom of the page to see the page 'thumbnails' clicking on the thumbnails will provide each page. To enlarge, use the % function on the left to get a beautiful reproduction of the manuscript page.
Again, thanks Jorge!
