Translations for fence in French

Here are paragraphs from public domain books translated:
The boarders swarmed over the fence like monkeys. Squire and Gray fired again and yet again; three men fell, one forward into the inclosure, two back on the outside. But of these, one was evidently more frightened than hurt, for he was on his feet again in a crack, and instantly disappeared among the trees. Telle une bande de singes, les assaillants surgirent au haut de la clôture. Le chevalier et Gray tirèrent coup sur coup : trois hommes tombèrent, l’un tête première dans le retranchement, deux à la renverse, au-dehors. Mais l’un de ceux-ci était évidemment plus effrayé que blessé, car il se retrouva debout à la seconde, et disparut aussitôt parmi les arbres.
