In addition to his 6 pounder light artillery, General Taylor also made use of a pair of 18 pound siege guns.
The big guns were actually brought to supply to Fort Texas.
These were huge, heavy cannon pulled by teams of oxen.
The cast iron tubes alone weighed in at almost five thousand pounds.
Their immense weight limited them to staying on the Matamoros to Point Isabel Road.
Although they did not possess the mobility of much smaller 6 pounders, their range was much greater than that of the small field guns.
With an earth shaking roar, these big iron guns were capable of launching a solid round over fifteen hundred yards...more than twice the effective range of the 6 pounders.
Here at Palo Alto, General Taylor used them to hurl volleys of explosive shot and shell over at General Arista and his men, raining down chaos upon the soldados.
