The battle of Lyck, the victory of which has heretofore been attributed solely to Field Marshal von Hindenburg, would appear to have been won by his subordinate, Gen. Curt E. von Morgen, according to the following letter, written by Gen. von Morgen to his friend Dr. Eschenburg, Mayor of Lübeck, the city where, in peace times, Gen. von Morgen was stationed as commander of the Eighty-first Infantry Brigade. Gen. von Morgen is 56 years old. He has been in the army since 1878, when he was appointed Lieutenant in the Sixty-third Infantry Brigade. He served in the German campaign in the Kamerun in 1894 and suppressed the rebellion there in 1896 and 1897. In the latter year he served also in the Thessaly campaign, attached to the headquarters of Edhem Pasha, and in 1898 he accompanied the German Emperor on the latter's journey to Palestine. The General wrote: SUWALKI, Sept. 13. Yesterday, after a short fight, I captured Suwalki, and I am now seated in the Government Palace. This morning I marched into the city with my division, and was greeted at the city limits by a priest and the Mayor, who offered me bread and salt. (The Russian officials had fled.) It was a glorious moment for me. I have appointed a General Staff officer as Governor of the Government of Suwalki. To-morrow we continue to march against the enemy. The army of Rennenkampf is completely destroyed. Thirty thousand men captured. Rennenkampf and the Commander in Chief, Nicholas Nicholaiewitch, fled from Insterburg in civilian garb. The plan of the Russians was to get us into a pot, but it was frustrated. The Twelfth Russian Army Corps, which was advancing from the south to flank our army, was beaten by me on Sept. 7, at Bialla, and on Sept. 9 at Lyck and was forced back over the border. You know that I always yearned for martial achievements. I had never expected them to be as great and glorious as these, however. I owe them in the first place to the vigorous offensive and bravery of my troops. I was probably foolhardy on Sept. 9, when I attacked a force thrice my superior in numbers, and in a fortified position; but even if I had been beaten I should have carried out the task assigned to me, for this Russian corps could no longer take part in the decisive battle. And so, in the evening, I sent in my last battalion and attacked by storm the village of Bobern, lying on the left wing. This, my last effort, must so have impressed the Russians that they began the retirement that very night. On the morning of the 10th of September the last trenches were taken. My opponents were picked troops of the Russian Army--Finnish sharpshooters. Health conditions with me are tolerable.
