So, with Sugríva, borne o’erhead Ikshváku’s sons the legions led. Behind, the Vánar hosts pursued Their march in endless multitude. Some skimmed the surface of the wave, To some the air a passage gave.

In plain words: Rama and Lakshmana, the princes of the Ikshvaku family, ride across on the backs of Hanuman and Angad, leading the army with King Sugriva. Behind them the huge monkey army (the Vanars) follows, some running over the water and some flying through the air.
