On this date 150 years ago, for the first time in United States history, the Congress passed a national income tax bill which provided also for tariffs to aid in the war effort. These Congressional measures were to raise $500 million for Union support. The income tax of three percent was applicable to incomes exceeding $800 per year, but was never actually put into effect.
Another fort in the Southwest, Fort Stanton, in the New Mexico Territory, was evacuated by Federal troops. Further disturbances occurred in Missouri; Dug Springs was the site of a small clash between Federals led by Nathaniel Lyon and pro-secessionists under General McCulloch`s command. General Fremont sent reinforcements to General Lyon who anticipated continued unrest in southwest Missouri.
