介绍（中）	亚历山大·加德纳在记录了安提坦大屠杀的两周后，回到战场拍摄亚伯拉罕·林肯总统的访问。总统驱车70英里前往马里兰州，向双方的伤员致敬，并与他的战地将军们进行了交谈。加德纳拍摄了大约25张照片，大部分是林肯和波托马克联邦军司令乔治·B·麦克莱伦将军紧张会面的肖像。他还为林肯与身材矮小的特勤局局长艾伦·平克顿（左）和约翰·麦克勒南将军合影。平克顿于1850年创立了同名侦探机构，事实证明，他作为军队间谍的顾问角色，是一个特别糟糕的军事情报收集者。许多人认为，他严重高估了罗伯特·E·李部队的实力——这一错误导致麦克莱伦在攻击敌人时极度谨慎，从而极大地延长了战争。
介绍（英）	Two weeks after he recorded the carnage at Antietam, Alexander Gardner returned to the battlefield to photograph the visit of President Abraham Lincoln. The president made the seventy-mile journey to Maryland to pay his respects to the wounded on both sides and to confer with his field generals. Gardner made about twenty-five photographs, mostly portraits of a strained meeting between Lincoln and General George B. McClellan, commander of the Union Army of the Potomac. He also made this formal field portrait of Lincoln posed with Allan Pinkerton, his diminutive Secret Service chief (left), and General John McClernand. Founder in 1850 of the eponymous detective agency, Pinkerton proved to be a particularly poor gatherer of military intelligence in his advisory role as a spy for the army. Many believe he significantly overestimated the strength of Robert E. Lee’s forces—an error that dramatically prolonged the war by contributing to McClellan’s extreme caution at attacking the enemy.
