I used the necessary update of server software to "re-program" the Martinien Online and added three kinds of search:
- officers losses per campaign ("Feldzüge")
- officers losses per place/town ("Orte")
- officers losses per unit ("Einheiten")
You find all three of them at http://www.napoleon-online.de/kriege_martinien.php and switch between them via the links above the headline.
Yes, it is in German but I think the fields to choose are quite self-explaining ... but I think to add an English interface after having added the rest of the Martinien content into the database.
