Four Brothers in Blue

These letters, collected and transcribed by Captain Robert Goldthwaite Carter in the 1870s, are among the finest primary sources on the daily life of the Union soldier in the Civil War. Robert and his three brothers all saw action with the Army of the Potomac under its various commanders, Generals McClellan, Burnside, Hooker, Meade, and Grant. At times in pairs but often in neighboring units, they fought on the battlefields of Bull Run, Antietam, Fredericksburg, Chancellorsville, Gettysburg, the Wilderness, and Petersburg.
