Pre-planning stages went well, and the general stratagem survived planetfall. Secure the central chinampas atoll by utilizing the archeotech and demolishing the manufactorum. Several Orks engaged us, and although there were no confirmed kills, we suppressed these skirmishers before the hordes engaged. Our techmarine and apothecary entered the administratum building and began to interface with the cogitation banks inside. Although the librarian and assault marine were unable to execute their entry into the manufactorum, they were instrumental in keeping the foul xenos at bay.
Plan update- Brother Joe should set off a charge on the southeastern portion of the manufactorum building, as we fall back, the orks will continue to advance. The blast might catch more orks, it will allow us entry into the frame of the building. Other suggestions?
