- William Steinway’s diary: “fighting on 2d Ave near 21st street, the 7th and 71st Regts arrive in the City more fighting on 2d & 1st Aves Stores broken into and plundered. Citizens organizing for defending private property, patrolling all night, burning of an Irish shanty near Central Park. During the day I have walked down to the store and back again in the eve. and watch all night til nearly 5 O Clock A.M. in the shop. Find to my horror that all the knapsacks of the 5th Regt has been moved to our basements in the store.” (Any sign of military presence is the invitation for arson. Unknown to William Steinway, his brother Charles has given permission for the soldiers of his regiment to bivouac on the premises.)
