[1] Weber enlisted in the Civil War as a private in the Forty-fourth Regiment New York Volunteer Infantry on August 7, 1861.

During this time Lieutenant Weber helped with recruiting for the newly formed One Hundred and Sixteenth New York regiment in the summer of 1862.

[3] On September 19, 1863, Weber attained the rank of colonel, two days before his twenty-first birthday, when he accepted command of the Eighty-ninth United States Colored Infantry.

[4] The 89th regiment was organized out of Port Hudson, Louisiana between October 8 and November 9, 1863, being designated the "18th Infantry, Corps d'Afrique".

[5][6] Early in 1864, during the Red River Campaign, Weber had the majority of his men reassigned leaving him only a handful.

These replacements were never acquired and Weber learned from a member of General Banks staff that his unit was to be consolidated.

His early efforts involved helping to organize the Republican Third Ward "Grant Club" and serving as its president in 1867.

In the area of local politics, Weber helped to reform the rules for the election of county committeemen.
