"for during the table top maneuvers, the theoretical American forces broke through and bombed Nagumo's carriers while their aircraft were away from their mother ships attacking Midway ... Lieutenant Commander Okumika, the umpire, ruled that the enemy had scored nine hits, sinking both Akagi and Kaga. But Ugaki would not suffer such lese majeste, and immediately overruled Okumiya, allowing only three hits, with Kaga sunk and Akagi slightly damaged. And later, when conducting the second phase practice, he blandly resurrected Kaga from her watery grave to participate in the New Caledonia and Fiji invasion"
