The Two Towers by J.R.R Tolkien (Harper Collins 1991, 2007) pp. 571-573
With some misgivings expressed by his company, Eomer gives three horses to Aragorn, Legolas and Gimli. Or I should say that he gives two, because Gimli refuses the offer, feeling no more at ease on the back of a horse than Sam Gamgee felt in the Elven boats of Lothlórien. Aragorn is asked to promise that he will return the horses to Meduseld, the golden hall of the King of Rohan and this he promises to do. After that the three hunters follow the orc trail until they come to the eaves of Fangorn Forest.
There they find the scene of the battle a great burning of the orc host, the burial mound for the fifteen members of Eomer’s company, but no sign of the hobbits. Eomer has told them that only orcs were burned but Gimli is sure that the hobbits must have been among them.

“It will be hard news for Frodo, if he lives to hear it; and hard to for the old hobbit who waits in Rivendell. Elrond was against their coming.”
“But Gandalf was not,” said Legolas.
“But Gandalf chose to come himself, and he was the first to be lost,” answered Gimli. “His foresight failed him.”
Gimli bases his judgement regarding the wisdom of a choice upon one thing only; whether the choice leads to a successful outcome. Gandalf fell in Moria at the Bridge of Khazad-dûm in the battle against the Balrog. Gimli fears that Merry and Pippin have fallen in the battle under the eaves of Fangorn Forest. Gandalf chose to accompany the Fellowship on its mission to destroy the Ring. Gandalf persuaded Elrond to allow the young hobbits to be a part of their company and it seems that they too are lost. Gimli is clear that Gandalf’s wisdom failed him as did his foresight.

To be fair to Gimli, Merry and Pippin feel the same way about the wisdom of their desire to go with Frodo and Sam. At least they feel that way while they are prisoners of the orcs. “I wish Gandalf had never persuaded Elrond to let us come,” says Merry. And who can blame him for feeling that way while he is trussed up like a piece of baggage and carried by his orc captors.
But Aragorn thinks differently. He too tried to persuade Gandalf not to go to Moria because he had a foreboding that something would befall Gandalf there. We are not told what he thought about Merry and Pippin going with the Company. His first impression of them, based upon his encounter with the hobbits at the Prancing Pony in Bree, had not been encouraging. But his respect for them grows on the journey to Rivendell as he realises that they are made of sterner stuff than he first thought. But he recognises that there are reasons for choices that outweigh any considerations the success or otherwise of the venture. Friendship is one of them. Merry and Pippin simply could not abandon Frodo and Sam just as Gimli could not abandon Legolas, just as they could not abandon the young hobbits.
The other reason is Aragorn’s own choice to go with the Fellowship. He must fulfil his destiny as the heir of Eärendil, as the heir of Isildur. Either he will succeed, thus becoming King of Gondor and of Arnor and winning the hand of Arwen, or he will fall in the attempt and be the last of his line. He can refuse the attempt but to do so will be to refuse hope both for himself and for the free peoples of Middle-earth. Like Denethor later he would have to accept that “the West has failed”. He does not know whether he will succeed or not. Indeed after the fall of Gandalf he has very little hope that he will. But he must go on, perhaps with failure the only outcome.
“The counsel of Gandalf was not founded on foreknowledge of safety, for himself or others… There are things that it is better to begin than to refuse, even though the end may be dark.”
