  • 2. Bergjegerdivisjons Felttog Gjennom Helgeland I 1940 —
    Fakultet for humaniora, samfunnsvitenskap og lærerutdanning – Institutt for historie og religionsvitenskap 2. bergjegerdivisjons felttog gjennom Helgeland i 1940 — Alexander Christopher Poulton Masteroppgave i historie ved lektorutdanninga His-3980 Mai 2016 I Sammendrag Denne avhandlingen tar for seg 2. bergjegerdivisjons felttoget gjennom Helgeland 1940. Denne divisjonen hadde som mål å komme til unnsetning til Narvik så fort som mulig. General Dietl og hans 3. bergjegerdivisjon var avskåret fra resten av det okkuperte Norge ved våren 1940. I tillegg vil masteroppgaven se på noen utvalgte hendelser ved felttoget i et kontrafaktisk lys for å kunne se hva som kunne ha skjedd ved våren 1940. I avhandlingen har jeg brukt kilder ved Arkiv i Nordland i Bodø og relevant litteratur om andre verdenskrig i Norge og Europa. Jeg har beskrevet det tyske felttoget til 2. bergjegerdivisjon, med spesielt fokus på den forreste bataljonen, Sorkobataljonen. Noen hendelser blir analysert for å se hva som kunne skjedd annerledes, innenfor rimelighetens grenser. For å lettere forstå de hendelsene i Helgeland og hvordan det kunne ha gått annerledes har jeg også tatt for meg noen bakenforliggende hendelser. For å forstå hvorfor hendelsene utviklet seg som de gjorde mener jeg det er viktig å se felttoget i Helgeland i sammenheng med krigen i Europa. Jeg vil også beskrive de styrkene som kom i land ved Namsos og Åndalsnes. Den britiske styrken i Helgeland besto av fem uavhengige britiske kompani, små styrker av Scots Guards og Irish Guards. I regionen var det også styrker fra det norske infanteriregiment 14. Bergjegernes felttog gjennom Helgeland var vanskelig for de britiske og norske soldatene å stoppe.

The estimated budget for the project is 42 Million Norwegian Kroners. Quick clay is one of the seven work packages of the project. More information about the project can be obtained at www.naturfare.no As a part of the on-going collaboration, NGI has been given a task to do a pre-study on the mobility of landslides in quick clays. The report presents results from numerical simulations carried-out on a few well documented quick clay landslides with BING, DAN3D and MssMov2D.

    Til berørte parter, offentlige instanser og interesseorganisasjoner jf. Adresseliste Vår ref.: Karl-Johan Lenningsvik Hemnesberget 04.04.2017 VARSEL OM OPPSTART AV DETALJREGULERING FOR TORGGATA 7 I RANA KOMMUNE På vegne av Johansen Maskin AS varsler Tanken arkitektur AS i henhold til plan- og bygningsloven § 12-8 om oppstart av følgende planarbeid, samtidig som at forslag til planprogram sendes på høring og legges ut til offentlig ettersyn: Detaljregulering for Finneidfjord grustak – boligbebyggelse i tettbygd strøk. Plandokumenter finnes på www.tankenark.no. Planområdet, eksisterende situasjon og gjeldende regulering Planområdet ligger ved Fv. 808 på Finneidfjord – gnr. 53/5 og 53/73. Planområdet ligger i et tidligere grustak mellom Hemnesveien (FV. 808) og boligfeltet langs Storhaugveien like nord for området. Nord og øst for grustaket er etablert som boligfelt med avkjørsel fra fylkesveien i sør via Haugabakken, og i nord-øst fra Hagaveien. Det er lokalisert ca. 40 boliger i nærområdet. Området som er aktuelt for utbygging ligger i ei sørvendt li med gode solforhold og sentral beliggenhet i forhold til Fylkesvei 808 til Hemnesberget og nært E6 ca. 1 km østover. Hensikten med planen er å tilrettelegge for boligbebyggelse sentralt på Finneidfjord. Det vil reguleres inn 8-10 boligtomter i planen. Planområdet avgrenses som vist i vedlegg. Endelig plangrense kan bli justert som følge av planprosessen. Forslagsstiller, i samråd med Hemnes kommune har vurdert at planen faller under krav om konsekvensutredning etter plan- og bygningsloven §§ 4-1 og 4-2. Forslag til planprogram legges som vedlegg i dette varselet. Gjeldene plan for området er kommuneplanens arealdel og er regulert til LNF-formål.
