I have not forgotten you. I received you e-mail. I am trying to locate some Russian General Staff maps pre-1917.
Dźiana (sic): Latvian Daugava in other languages: Dyna – Düna – Двина – Дзьвіна – Dźwina – Dvina - Väina. http://pl.wikipedia.org/wiki/D%C5%BAwina
I note: "The King of Naples continues to follow the enemy's rear-guard. On the 5th he met the enemy's cavalry in a position upon the Dwina. He caused it to be charged by the brigade of light cavalry, commanded by General Baron Subervie. The Prussian regiments, the Wirtembergers and Poles, which, form a part of this brigade, charged with the greatest intrepidity. They overturned a line of Russian dragoons and hussars, and took 200 prisoners, with their horses. When they arrived on the other side of the Dwina, they broke down the bridges, and showed a disposition to defend the passage of the river. General Count Montbrun then brought up his live batteries of light artillery, which, during several hours, carried destruction into the ranks of the enemy. The loss of the Russians has been considerable." https://books.google.com/books?id=0a4TAAAAYAAJ&pg=PT194 In French: https://books.google.com/books?id=C6s7AAAAMAAJ&pg=PA13
Note several things: The river in called "Dziana" but the battle does not take place "at Dziana" but "upon the Dziana". It would appear there was a transcription error with "Dziana" for the Polish "Dźwina". The French reports seem to use Polish names for locations.
"On the 12th, General Baron Pajol, who was at Ighouman, sent Captain Vandois, .with 50 cavalry, to Khaloui. This detachment took there a park of 200 carriages, belonging to Bagration’s corps, and made prisoners six Officers,. 200 cannoniers, 300 men attached to the train, and 800 fine artillery horses. Captain Vandois, finding himself 15 leagues distant from the army, did not think it practicable to carry off this convoy, and burnt it. He has brought with him the horses and the prisoners." https://books.google.com/books?id=97o5AQAAMAAJ&pg=PA281 French text: https://books.google.com/books?id=FX1BAAAAcAAJ&pg=PA285
A trail of bread crumbs: "La campagne de Russie commence. Pajol s'empare d'Ochmiano le 30 juin, et entre à Minsk le 8 juillet. Il parvient à Ighouman le 11 juillet et surveille la Bérésina"
