William Sickles was born in New York and would sign up in Wisconsin, and also to serve with the 7th Illinois unit, but in company B.
Both men are pictured here in a newspaper article about the presentation. Their MOH's are the medal on the left as you look at the picture. It is not the army's Civil War version of the medal but a later version from the 1890's. The other is probably either the Civil War Iron Brigade medal or a Grand Army of the Republic badge depicting the Iron Brigade's badge. The hats they are wearing may also have been the 1858 designed CW army "Hardee Hats" worn by many infantry units. (This famous brigade consisted of 5 diferrent units and each is identified on an arm of the badge.)
O'Connor would serve throughout the Civil War with the unit and by the time the south's General Lee surrendered at Appomattix, with the 7th on hand, O'Connor would have already participated in at least 30 different battles, been wounded and even been taken as a POW for a short time before being released back to his unit.
It would be at the end of March in 1865 that O'connor's unit would be moving forth with the attempts to drive Lee's army out of Petersburg that he would earn his Medal of Honor at Gravelly Run, Virginia. After one of his unit officer's was captured by the enemy, he found where the man was being held. Both he and Sickles charged the position, took 3 of the nine capturers as Prisoners of War, scattered 6 others and of course freed his own officer. The following day both he and Sickles again would be in the thick of battle and would end up in hand to hand fighting with the enemy. When all was over, one Confederate officer lay dead and the two Sergeants were headed off back to the safety of their own lines. And they carried with them the enemy's colours. But luck would change when they became surrounded and had to surrender the colours and themselves becoming POW's shortly before release and freedom to rejoin their unit. Both Sergeants would later be awarded the Medal of Honor with citations for both of these events.
Albert O'Connor died on 17 Feb., 1928. That was 85 years ago this month. And the official citation and awarding of his medal was dated on today's date back in 1917.
