The Irish Transvaal Brigade, also known as the Wreckers' Corps, was organised by
John MacBride, who was then employed at the Rand Mines. Most of the
company-strength Brigade were
Irish or
Irish-American miners living in the
Transvaal who were willing to fight with the Boers against the
British. The Brigade was bolstered during its campaign by a contingent of volunteers who came from
Chicago and by a variety of Irish volunteers who travelled from America and Ireland to join the Brigade. The Brigade would come to be known as MacBride's Brigade, after their commander, John MacBride. It was operational from September 1899 to September 1900, when the brigade fought in about 20 engagements, with 18 men killed and about 70 wounded from a complement of no more than about 300 men at any one time. When it disbanded, most of the men crossed into
Mozambique, which was a colony of neutral
Portugal. Colonel
John YF Blake, a former
US Army officer was the brigade's commander. When he was wounded, his second-in-command, Major
John MacBride, took command. Until the Siege of Ladysmith, the commandos were involved in guarding the artillery under Carolus Johannes Trichardt. The brigade also provided signal service at the Battle of
Modderspruit. At the
Siege of Ladysmith, they serviced the famous Boer artillery piece, called
Long Tom, and they fought at the
Battle of Colenso. Having worked in the gold mines, they had a well-deserved reputation as
demolition experts. They delayed the British advance on
Pretoria by blowing up bridges. The brigade disbanded after the
Battle of Bergendal. The brigade received letters of thanks before they left South Africa from State Secretary
Francis William Reitz, Commandant-General
Louis Botha and General
Ben Viljoen. ==Second commando==
