i read it in wiki that kaido was gonna intervene whitebeard when was gonna save Ace...but shanks stopped him and is currently fighting him...somewhere!!

here is the wiki explaination:
"Current Events

To the horror of the Marines, reports came in that Shanks had intercepted Kaidou who was advancing to attack Whitebeard at the time as he progressed to save Ace. While the two captains had come to a stalemate, the Marines were afraid what a fight between the two may have led to."
