I noticed in the battle of helms deep,the elf suddenly dissapear.even though just moments before, they were seen carrying gimli(dragging,actually)to the keep.they probably been killed off,but come on,at leastna few can escape to the keep.the killed off theory seem more likely though,given that most if the elves were killed in the wall,and the uruks,at the end,managed to cut rohan and the elf's troops to the keep and kille almost all of them.so yeah,the could bekilled off.
