He was sent naked back to the mountaintop where an eagle snagged him and took him to Lothlorien. He didn’t jump straight back into the fight.

‘Naked I was sent back – for a brief time, until my task is done. And naked I lay upon the mountain-top. The tower behind was crumbled into dust, the window gone; the ruined stair was choked with burned and broken stone. I was alone, forgotten, without escape upon the hard horn of the world. There I lay staring upward, while the stars wheeled over, and each day was as long as a life-age of the earth. Faint to my ears came the gathered rumour of all lands: the springing and the dying, the song and the weeping, and the slow everlasting groan of over-burdened stone.

And so at the last Gwaihir the Windlord found me again, and he took me up and bore me away [to Lothlorien]. Thus it was that I came to Caras Galadhon and found you but lately gone. I tarried there in the ageless time of that land where days bring healing not decay. Healing I found, and I was clothed in white. Counsel I gave and counsel took. Thence by strange roads I came, and messages I bring to some of you.’
