The battle of Boimie consisted of a persevering effort on the part of the enemy to force the passage of a dyke (_k_), under the protection of the fire of a strong battery of artillery (_e_). On our side, every effort was directed to the making of the passage of that dyke as destructive as possible to the enemy. For this object our arrangements were made as follows. On the night of the 14th, we destroyed the bridges (_m_) over the small river of Kostrzyn, which traverses the dyke or main road in two places. Not far from the nearest bridge, a defence of branches of trees (_n_) was thrown together, which having been well placed, made a good cover for our marksmen, and for a battalion of infantry (_o_), which were concealed behind them. The fire of grape from the enemy's artillery was rendered ineffective to a great degree by this mass of trees. Upon the nearest elevations of ground (B), general Zymirski placed eighteen pieces of cannon (_a_), the fire of which was concentrated upon the dyke. By this means every attempt of the enemy to re-construct the bridge was made to cost him a severe loss, and was rendered ineffectual. The main body of our forces was placed without the reach of the enemy's artillery. On the left of our position, at the distance of about half a mile, a small road (_p_) led to Dobre, and that road was intersected by the small river above mentioned. The bridge which continued the road over this river was destroyed by us, and a small detachment placed there to prevent its reconstruction and its passage by the enemy. [Illustration: _Boimie_ III] Such was the distribution of the small force which, profiting by the strength of its position, was able to meet the attacks of the numerous body of the enemy commanded by marshal Diebitsch in person, and which were renewed during the whole day. The details of the action are as follows:--At about 9 o'clock on the morning of the 15th, the Russian force commenced debouching from the forests which border the main road, between Mingosy and Boimie, and deploying to the right and left, took position. In a short time the field was covered with the enemy's masses. His force consisted of twelve regiments of infantry (_f_), six of cavalry (_g_), and sixty pieces of cannon. It was at about noon that the enemy placed his artillery upon the heights (A) above the bridge and commenced his fire. After continuing for some time this fire, which was but occasionally answered by our artillery, the enemy sent several battalions in column, upon the bridge, a part of which force engaged in the repair of the bridge, and the rest attempted to make the passage. Every approach of the enemy was met with a warm fire from behind the defence of trees above mentioned, and our artillery at the same time opened a destructive fire of grape upon the bridge. The attempts of the enemy were renewed for some hours, in vain.
