Groce's plantation becomes temporary capital of Texas
On this day in 1836, the new government of Texas began a three-day stay at Groce's Retreat, Jared E. Groce's plantation home, in what is now southwestern Grimes County. President David G. Burnet and his cabinet sought sanctuary there as they retreated from Washington-on-the-Brazos to Harrisburg. Groce's house was used as the capital of the Republic of Texas until March 21.
