The forces of general Gielgud having thus crossed the Niemen, passed a night at Rewdany, and the next day [_Plan_ XXXIV.] marched on to Czaykiszki (1), in the direction of Keydany. We cannot understand why general Gielgud did not attack Malinowski (_b_), who passed at the distance of half a league from us, at the head of 6,000 men, on his march to Wilno. It is, we believe, a thing unheard of in the history of military affairs, that an inferior force should be suffered to pass, unmolested, so near a hostile army. It discovered the very last degree of carelessness, to enter a country in the occupation of the enemy, without sending out even the ordinary reconnoissances. General Malinowski,[70] with his corps, which ought to have fallen into our hands, escaped, and made the second Russian force which had owed its safety to our negligence, and contributed a new accession to the forces which we should have to contend with. [Illustration: _XXXIV._ ] On the 10th of June, the corps arrived at Keydany (2), in which place it was joined by general Chlapowski with his corps, which had so successfully traversed the departments of Bialystok and Grodno. This force, which, on quitting Xienzopol, amounted to scarce 1,000 men, received reinforcements of cavalry and infantry, from the insurgents of the provinces, through which it had passed.[71] From the new forces, ten squadrons of cavalry, counting nearly 1,200 horse, and two battalions of infantry, amounting to nearly 1,800 men, were formed. On the 11th of June, the united corps quitted Keydany, to march to Zeymy (3), where we arrived at night. In this little town we remained several days, we know not for what object. From this place general Chlapowski was sent with a detachment, consisting of the 1st regiment of lancers and five pieces of light artillery, to make reconnoissances in the direction of Wilno. The new forces of which we have just spoken, were attached to the main body, under general Gielgud. A few hundred of insurgent cavalry of Lithuania also arrived at Zeymy, which were joined to the lancers of Poznan and the 3d regiment of lancers. On the day of our departure, general Szymanowski received orders to leave for Polonga with a small corps of insurgents (_c_) from the department of Szawla. This corps consisted of 1,500 infantry, 400 light cavalry, and two pieces of cannon.
