hints：Antietam Creek;Gen. Robert E. Lee;Gen. George McClellan; Emancipation Proclamation
September 17, 1862, was the bloodiest day of the war. The two armies met at Antietam Creek in Maryland. Gen. Robert E. Lee and his confederate army failed to force back the union troops led by Gen. George McClellan. Lee escaped with his army. The battle was not decisive, but it was politically important. Britain and France had planned to recognize the confederacy, but they delayed. The south never received the help it desperately needed. Later in 1862, President Lincoln issued a preliminary Emancipation Proclamation that freed all slaves in the confederate states. It also allowed African Americans into the Union Army. The north fought to keep the union together and to end slavery.
1862年9月17日，是战争中最血腥的一天。两军相遇在安蒂特姆河在马里兰州。罗伯特·李将军和他的同盟军失败，迫使联盟由乔治麦克莱伦将军率领的部队。李和他的军队逃脱。这场战争是不是决定性的，但在政治上是重要的。英国和法国曾计划承认邦联，但他们推迟。南部从未收到急需的帮助。后来在1862年，林肯总统颁布了初步解放宣言，释放所有同盟国家奴隶。它也允许进入联盟军队的非裔美国人。北部战斗以保持联盟一起以及结束奴隶制。
