Our campaign around Gettysburg / Being a memorial of what was endured, suffered and accomplished by the Twenty-third regiment (N. Y. S. N. G.) and other regiments associated with them, in their Pennsylvania and Maryland campaign, during the second rebel invasion of the loyal states in June-July, 1863

A firsthand regimental memoir recounts the June–July 1863 Pennsylvania and Maryland campaign from the perspective of a New York militia regiment, describing marches, picket duty, bivouac hardships, and the militia's role in defending the Susquehanna Valley and Harrisburg. It chronicles skirmishes, the burning of a bridge, the presence and movements of opposing forces, and the militia's readiness to reinforce Gettysburg, while reflecting on morale, command decisions, and the uncertain impact of reinforcements on the larger battle. Interspersed are orders, official reports, and tributes to officers and comrades, combining tactical narration with personal remembrance and argument for the militia's contribution to the campaign.
