[LOTR] Why does Isildur flee at Gladden Fields instead of stand and fight with his men?

He fought Sauron face to face and was a skilled and honorable warrior. Did the influence of the Ring make him cowardly? Was he being evacuated to safety Secret Service to US President style?

There's a difference between fighting in a war surrounded by men and fighting in an ambush where most of your much smaller amount of men are being killed. But the thing is, the nature of The Ring entices you to use it. And without knowledge of it's true purpose, the only thing you could really use it for is hiding. 

The Ring then tried to get him killed - getting found by an orc would make it pretty easy for Sauron or some other powerful being to discover - but made the slight miscalculation of being in a river. But if it hadn't done so, the plan would have worked. Isildur would have escaped the deadly ambush and returned alive to his family and kingdom.
