"The soldiers fall down from the horses."

Translation: A katonák leesnek a lóról.

[IldikoPapa]

'Horses' is in plural, so it is not lóról but lovakról

[MiklosBalo2]

Different meaning: with "lóról" it means two or more solder from one (or more) horse, with "lovakról" it means two or more solders from at least two horse. I prefer "lovakról", because the english sentence includes "horses".
