Indeed, here is a copy of the Texas Ordinance of Secession and it a good example of railing against the North, not only for violating the contract of the U.S. Constitution but the terms of Annexation as well. BTW, the last signatory is Sam A. Willson. Like many of the others, he served in the War. He was a captain in the 1st TX Infantry. In Feb. 1861, he was a 26 year old lawyer and probably the only delegate born in Texas. The very firt signature is O.M. Roberts, who served in the War, in the legislature and became Governor in post Reconstruction Texas.

The Federal Government, while but partially under the control of these our unnatural and sectional enemies, has for years almost entirely failed to protect the lives and property of the people of Texas against the Indian savages on our border, and more recently against the murderous forays of banditti from the neighboring territory of Mexico; and when our State government has expended large amounts for such purpose, the Federal Government has refused reimbursement therefor, thus rendering our condition more insecure and harassing than it was during the existence of the Republic of Texas.

These and other wrongs we have patiently borne in the vain hope that a returning sense of justice and humanity would induce a different course of administration.

When we advert to the course of individual non-slave-holding States, and that a majority of their citizens, our grievances assume far greater magnitude.

The States of Maine, Vermont, New Hampshire, Connecticut, Rhode Island, Massachusetts, New York, Pennsylvania, Ohio, Wisconsin, Michigan and Iowa, by solemn legislative enactments, have deliberately, directly or indirectly violated the 3rd clause of the 2nd section of the 4th article of the federal constitution, and laws passed in pursuance thereof; thereby annulling a material provision of the compact, designed by its framers to perpetuate amity between the members of the confederacy and to secure the rights of the slave-holding States in their domestic institutions--a provision founded in justice and wisdom, and without the enforcement of which the compact fails to accomplish the object of its creation. Some of those States have imposed high fines and degrading penalties upon any of their citizens or officers who may carry out in good faith that provision of the compact, or the federal laws enacted in accordance therewith.
