P. I. Bagrations secret order for the force at Borisov to retreat.
25 June 1812, No. 387. On the march, in Mir.
To Colonel Gresser. Having been informed that the enemy must be in Minsk, I am ordering that as soon as they approach within 20 miles [30 verst] of Borisov, do not wait for further orders but rather spike all your guns [zaklepat vse pushki], dump them into the water, and yourself with your command withdraw to Bobruisk and place yourself under the command of Major General Ignatev.
