Peter and Laust reach Dannevirke, where they meet their new Captain - a familiar face from the estate back home - but not exactly a happy reunion. Laust and Inge continue their secret letter writing but an incorrectly delivered letter causes serious consequences for the relationship between the otherwise inseparable brothers. Dannevirke turns out not to be nearly as impregnable as people have been boasting, and General De Meza decides, against the will of the powers that be in Copenhagen, to withdraw from Dannevirke to Dybbøl.
