Checking the webpage of the Danish scholar Per Bilde, I discovered that he has posted a copy of an article on Philo on as a Polemist and a Political Apologist, on his webpage.
The article concerned was first published in Danish as: Per Bilde, “Filon som polemiker og politisk apologet. En undersøgelse af de to historiske skrifter Mod Flaccus (In Flaccum) og Om delegationen til Gaius (De legationer ad Gaium), in: Anders Klostergaard Petersen, Jesper Hyldahl og Kåre Sigvalg Fuglseth (red.): Perspektiver på jødisk apologetik, København 2007, 155-179.
This was then translated into English and published as: P. Bilde, ‘Philo as a Polemist and a Political Apologist: an Investigation of his Two Historical Treatises Against Flaccus and The Embassy to Gaius,’ in G. Hinge and J. Krasilnikoff (edd.), Alexandria: a Cultural and Religious Melting Pot (Aarhus 2009) 97–114. It is this English version that is posted on his webpage.

Another study, not unrelated to Philo, and closely related to another of his published studies, is also available on one of his webpages:Die Caligula-Krise im jüdischen Palästina im Jahre 40-41 n. Chr.
This is closely related to his published study “Der Konflikt zwischen Gaius Caligula und den Juden über die Aufstellung einer Kaiserstatue im Tempel von Jerusalem”, i: Anne Lykke und Friedrich T. Schipper: Kult und Macht. Religion und Herrschaft im syro-palæstinischen Raum. Studien zu ihrer Wechselbeziehung in hellenistisch-römischer Zeit. Tübingen: Mohr Siebeck 2011, 9-48.
