Hardly. The yankee government spent the last three years of the war launching invasion after invasion after invasion against Texas. Every single one of them collapsed or was turned away at the border.
Nor were they small or peripheral invasions. One of them used over 20 navy ships and a second, the Red River Campaign had over 40 - the largest inland fleet assembled during the entire war. The bumbling invasion force on the Red River Campaign consisted of an operation that, in full, entailed almost 50,000 men. As always, capitan, you simply do not like the fact that your beloved yankees got their asses handed to them again and again and again in Texas no matter what they threw at the state. So instead of admitting the facts you spin them, obscure them, and pretend as if they weren't anything worthy of mention.
All of the significant battles in the Red River Campaign were fought in ... LOUISIANA.
You crack me up.
