But to forestall the French with his whole army was impossible.
Rostov, who had completely forgotten Denisov, not wishing anyone to forestall him, threw off his fur coat and ran on tiptoe through the large dark ballroom.
Bagration was to make this march without resting, and to halt facing Vienna with Znaim to his rear, and if he succeeded in forestalling the French he was to delay them as long as possible.
If he reached Znaim before the French, there would be great hope of saving the army; to let the French forestall him at Znaim meant the exposure of his whole army to a disgrace such as that of Ulm, or to utter destruction.
You have been forestalled, my dear!
If Kutuzov decided to retreat along the road from Krems to Olmutz, to unite with the troops arriving from Russia, he risked being forestalled on that road by the French who had crossed the Vienna bridge, and encumbered by his baggage and transport, having to accept battle on the march against an enemy three times as strong, who would hem him in from two sides.
There are no more uses of "forestall" in the book.
