Lieutenant Frank Haskell was an aid to General Gibbon during the Gettysburg campaign and witnessed many of the historic events that occurred during those three days. His detail-filled essay/letter written just weeks after the battle chronicles what he witnessed during those dark days. He was eating lunch with several generals including General Meade and his staff near the Leister house when the Confederate bombardment that preceded Picket's Charge began. He describes the scene in the Leister farm yard where orderlies and curriers had their horses tied to many of the trees. During the cannonade, many of the Confederate shells aimed at Cemetery Ridge overshot their target and struck all around Meade's HQ on the Taneytown Road. Haskell then describes how many of the horses were killed still tied to the trees. A few days later, Alexander Gardner recorded the scene in his iconic photographs of Meade's HQ, the widow Leister's farm. In this detail from Gardner's photo, you can see the very horses described by Haskell, many still tied to the trees just as he said. I count as many as nine, maybe ten of the four-legged heroes lying dead under the trees. Haskell then accompanied General Gibbon up to Cemetery Ridge where he witnessed the effects of the bombardment followed by the grand charge. His flourishing detailed accounts are well worth reading.
