Maybe he did. Maybe not. But the army, naval and air forces on the ground in Hawaii had no advance warning.
Actually they did. George Marshall sent cables to Short and Kimmel several days prior advising that negotiations with the Japs were at an impasse. He declared in one dispatch to consider this a “war warning” and that events were about to occur, exactly where is TBD, but pay attention.
The Ward fired on a sub attempting to enter the channel 2+ hours prior to the attack.
Radar on Opana Point detected the inbound attack wave at 0700 and were told, “not to worry about it”.
The real travesty was the day after the attack on Pearl. MacArthur had a full 24 hr notification to prepare, but sat on his fat ass and allowed the Japs to decimate Clark without lifting a finger...should have been court martialed for negligence.
