Translations for hastily in French

Here are paragraphs from public domain books translated:

He had risen from his position to his hands and knees, and though his leg obviously hurt him pretty sharply when he moved—for I could hear him stifle a groan—yet it was at a good, rattling rate that he traiied himself across the deck. In half a minute he had reached the port scuppers, and picked out of a coil of rope a long knife, or rather a short dirk, discolored to the hilt with blood. He looked upon it for a moment, thrusting forth his under jaw, tried the point upon his hand, and then hastily concealing it in the bosom of his jacket, trundled back again into his old place against the bulwark.

Il s’était dressé sur les mains et les genoux, et, bien que sa jambe le fît beaucoup souffrir à chaque mouvement — car je l’entendis étouffer une plainte — il n’en traversa pas moins le pont à une bonne allure. En une demi-minute, il avait atteint les dalots de bâbord, et extrait d’un rouleau de filin un long coutelas ou plutôt un court poignard, teinté de sang jusqu’à la garde. Il le considéra d’un air féroce, en essaya la pointe sur sa main, puis, le cachant en hâte sous sa vareuse, regagna précipitamment sa place primitive contre le bastingage.
