Diary Entry:
This morning we left Camp Andrew, or Stewart’s Grove as the place was formerly called. I was detailed with seven others to look after the commissary stores and therefore had to remain in Camp Andrew until near 3 o’c. P.M. On my way to our new camp at Ft Marshall, Ft Murray, Snake Hill or Potters Hill, whichever it may be called, I visited Pattersons Park, which is garrisoned by Co. “K” of our Regt. The Park is a pleasant place. It is used partly as a hospital. 62 Regts. are represented there by sick and wounded soldiers.

On my arrival here (Ft Marshall) I found Companies “B,” “E,” “F,” and “H” were quartered in the Ft. and “A,” “C,” “D,” “G,” and “I,” in quarters outside. The hill on which the Ft is built commands the city, the River, Ft McHenry, Federal Hill, and Pattersons Park. The fort is an earthwork, mounts 33 guns of 42, 32 and 24 pounds each.

See scanned diary pages 13 and 14 and a map of Cyrus’ Progress.

More Information:
After staying at Baltimore’s Camp Andrew for nearly a month, Cyrus received orders to move to Fort Marshall in the eastern part of the city.

Fort Marshall occupied the precipice known as Snake Hill, Murray’s Hill, or Mount Washington near the intersection of Foster Avenue and Conkling Streets.

At one point Fort Marshall was armed with from 50 to 60 guns of 32- and 42-pounders, in addition to Columbiads (large-caliber, smooth bore, muzzle loaded cannon). No traces of the fort remains today and it is now the site of Sacred Heart Catholic Church.

During the Civil War, part of Patterson Park became Camp Washburn and a hospital (Camp Patterson Park) was also established there.
