treaties must be enforced on both sides in order for peace and mutual respect to develop. The 4th Frontier War (1811-1812) In 1811 he was commissioned as an ensign in the Cape Regiment, took part in the 4th Cape Frontier War (1811–12), and in the campaign against Ndlambe. During this time, Andries served as aide-de-camp to his father, Anders Stockenström. When his father was ambushed and killed, the young Andries rode from Bruintjieshoogte with 18 mounted burghers. He hunted down and overtook a number of the killers near Doringnek, slaying 13 of them. Upon returning from Doringnek, Andries was appointed to his father's position in command of the burgher forces. Following Ndlambe's expulsion, he assisted Colonel John Graham in fortifying the Fish River frontier. Governor Sir John Cradock then appointed him as assistant landdrost of Graaff-Reinet, stationed initially at Van Stadensdam on the (upper) Fish River, and afterwards at the newly founded town of Cradock. Andries retained his commission as his duties remained mostly of a military nature. In a rapid and successful campaign in 1813, he struck across the Fish River against Xhosa tribes that had violated the new frontier, and in May 1814 he was appointed a lieutenant in the Cape Regiment. He rose through the ranks rapidly after fighting in the fourth frontier war. The 5th Frontier War (1818-1819) Due in part to overcrowding, a civil war broke out between the amaNgqika (Ngqika Xhosa) and the amaGcaleka (Gcaleka Xhosa). As the Cape had signed a defence treaty with Ngqika, it was legally required to respond to Ngqika's request for military assistance in 1818. Stockenström was thus ordered to lead his commando, as an ally of Ngqika, against Ndlambe's amaGcaleka. After swiftly intercepting and defeating the Gcaleka army, he withdrew his commando and stationed his Graaff-Reinet burghers to defend the left flank at the Kat River. However, after the Cape withdrawal, the amaGcaleka regrouped in 1819 and this time invaded the Cape Colony itself, attacking Grahamstown. Stockenström thus took to the field again. He was first ordered to position his Graaff-Reinet commando to meet any attack across the northern section of the frontier. Then while the Cape, Stellenbosch and Swellendam commandos advanced against the main amaGcaleka army, Stockenström's Graaff-Reinet commando was ordered to clear insurgents from the dense bush in the Fish River area – previously regarded as impenetrable. After successfully implementing this supposedly impossible campaign, Stockenström was
