Prussian army Generalleutnant Albrecht von Stosch ended the practice of placing marines aboard warships. Instead he adopted a concept that became known as Infanterieismus. He would train seamen as naval infantry, qualified in using small arms and competent in infantry tactics and amphibious operations. That approach would position the Seebatallion as a compact, self-contained organization, roughly equivalent to the British Royal Marine Light Infantry. Enlargement of the battalion to six companies allowed a reorganization and the transfer of half of the battalion to Wilhelmshaven to form the II. Seebatallion. Both battalions were then increased in size to four companies. Scheduled exchanges of officers from the Prussian army brought current tactical thinking to the sea battalions.
