Despite the vast material that has been written about the Second World War, most literature mentions battleships in passing, giving little attention to a role that battleships filled- that of naval gunfire support for amphibious landings. The literature regarding the Navy’s older, obsolescent battleships such as the Texas is scarce. Using primary sources regarding the Texas and the evolution of naval gunfire doctrine from the pre-war and wartime periods, this study looks at the involvement of the Texas in the Second World War and how the Navy employed its oldest battleships. The amphibious landings of the war provided a role in which a ship’s speed and range became irrelevant when firing on fixed targets on an enemy beach. This work provides a look at a little discussed, though widely used aspect of the Second World War and helps further discussion regarding the evolution of the US navy.

The United States Marine Corps and the United States Navy developed during the interwar period a doctrine that addressed the problems inherent in the substitution of naval gunfire for artillery support in an amphibious assault. The invasion of Betio Islet, Tarawa Atoll, in November of 1943 was the first test of this doctrine. It has been said many times since the war that the doctrine basically passed this test and that lessons learned at Tarawa increased the efficiency with which the Marine Corps and Navy applied the prewar doctrine during the rest of the war. An analysis of the planning and execution of naval bombardments in the Central Pacific Campaign, after the invasion of the Gilberts, does not support this claim. This analysis leads the researcher to three conclusions. First, the Japanese developed defenses against many of the effects of the gunfire support doctrine that blunted much of the force of American firepower. American planners were slow to recognize the implications of these changes and, consequently, were slow to react to them. Second, many naval commanders responsible for providing naval gunfire support for Central Pacific operations still equated tonnage of ordnance to effectiveness of bombardment, regardless of their frequent references to "the lessons of Tarawa." Finally, strategic concerns and outright ignorance played a large part in determining the use of naval gunfire, the first taking precedence over the "lessons" and the second leading to the ignoring of the "lessons" all together.

Denna undersökning har studerat ett lätt infanteriförbands användning av kombinerad bekämpning som metod för verkan under en amfibieoperation samt vilka aspekter som påverkade möjligheten till kombinerad bekämpning p.g.a. operationens amfibiska karaktär. Fallet har utgjorts av Parachute Regiments två bataljoner som under Falklandskriget utkämpade tre slag vid Darwin – Goose Green, Mount Longdon och Wireless Ridge. Som analysverktyg har använts Robert Leonhards teori om den kombinerade bekämpningens tre principer. Indikatorer på principerna har varit syften med verkan hämtade ur teorin om de grundläggande förmågorna. Två av slagen befanns endast delvis kännetecknas av Leonhards två första principer, principerna om kompletterande system och dilemman. Den tredje principen om fördelaktig terräng uppfylldes inte. Det tredje slaget regementet utkämpade kännetecknades helt igenom av Leonhards två första principer medan den tredje delvis beaktades. Undersökningen konstaterar att kombinerad bekämpning som metod för verkan kan utvecklas av ett lätt infanteriförband under en amfibieoperation. Dock ledde ofördelaktig disponering av förbandet i de aktuella fallen till att kombinerad bekämpning tidvis omöjliggjordes. Leonhards tredje princip tenderade att förringas. De specifikt amfibiska aspekterna avseende möjligheten till kombinerad bekämpning utgjordes främst av tillgången till fartygsartilleri, kraven på helikoptertransporterbart fältartilleri samt bristen på lätta trossfordon. / This dissertation has investigated how a light infantry force has used combined arms during an amphibious operation, specific factors related to the operations character affecting the possibility to develop combined arms have also been highlighted. The case chosen for the study was Parachute Regiments actions during the three battles of Darwin – Goose Green, Mount Longdon and Wireless Ridge during the Falklands War. As a analytical tool Robert Leonhard’s theory about the three principles of combined arms was used together with indicators borrowed from the theory about the warfighting functions purposes of fires. Two of the battles were found to be only partially characterized by Leonhard’s first two principles, complementary systems and dilemmas. The third principle about favorable terrain was neglected. The third battle was throughout characterized by the first two principles and to a larger extent than the former by the third principle. The dissertation concludes that light infantry can use combined arms during amphibious operations. The battles studied were, however, often characterized by unfavorable disposition of the force which affected the possibilities to use combined arms. Leonhard´s third principle was usually neglected. The most important amphibious aspects affecting the possibilities to combined arms were found to be naval gunfire support, light field artillery and the scarcity of light all-terrain vehicles.
