 On the return of the Japanese fleet to Hashirajima on 14 June the wounded were immediately transferred to naval hospitals ; most were classified as " secret patients " , placed in isolation wards and quarantined from other patients and their own families to keep this major defeat secret . The remaining officers and men were quickly dispersed to other units of the fleet and , without being allowed to see family or friends , were shipped to units in the South Pacific , where the majority died in battle . None of the flag officers or staff of the Combined Fleet was penalized , with Nagumo later being placed in command of the rebuilt carrier force .
