Headquarters, Camp at the head of a little bayou, Sunday, April 17, 1836:
Dear Fellow Texians,
We continued to march along the muddy road to Harrisburg, resting for the night at the head of a little bayou about six miles from Harrisburg. The days are now rather hot and quite uncomfortable with all of the water around. We are close to a forced march, as we believe that we are on an intercept course with the enemy.
As of this writing I have no confirmation of a report given by a civilian that Santa Anna himself has taken a small force and has rushed to Harrisburg to catch the new Texian government. The government had moved there from Washington, but had then departed for Galveston by way of Morgan’s point before Santa Anna‘s arrival. In an effort to catch the government, the Mexican army then proceeded to New Washington on Col. Morgan‘s point on Galveston Bay. The main body of the Mexican army is still on the Brazos at Thompson’s ferry. This is perhaps the opportunity we have been looking for, to confront the enemy while vulnerable with a decisive battle. The spirit of the men has risen to a higher pitch than I have witnessed on this whole campaign.
Respectfully yours, An Observer and aide-de-camp
Meanwhile the Mexican Army: After putting the town to the torch, Santa Anna left Harrisburg at 3 p.m. for New Washington. After a difficult crossing over Sims Bayou the army encountered Vince’s Bridge over Vince’s Bayou. The bridge was too shaky to handle the Mexican cannon so second in command Castrillion and a company of infantry were sent with the cannon around the headwater of Vince's. A terrific rainfall that evening so Santa Anna camped in or near William Vince’s cabin. Still no word from Gaona but should be approaching San Felipe. Urrea camped on the outskirts of the woods on the San Bernard river.
The Interim Government: President Burnet boards the Flash and is taken, with the rest of the cabinet, to Galveston where they will remain for the duration of the war.
