Johannesburg Vrijwilliger Corps & ZARPs
Early Role
Siegfried van Lier served as 1st Lieutenant Quartermaster for the Staff of Infantry in the Johannesburg Vrijwilliger Corps (JVC) and during the Anglo-Boer War as Lieutenant . He also held the position of Artillery Lieutenant in the Johannesburg Police Corps (ZARPs), one of the most famous and disciplined units of the Zuid-Afrikaansche Republiek (ZAR). His leadership placed him at the forefront of some of the fiercest battles of the war.
Battle of Berg-en-Dal (Dalmanutha), 27 August 1900
Commandant van Lier played a central role during the last pitched battle of the Anglo-Boer War at Berg-en-Dal. Alongside Commandant Ph.R. Oosthuizen and Lieutenant F. Pohlman, van Lier commanded a detachment of only 60–70 men positioned on an isolated kopje. Facing overwhelming odds, their small unit endured:
- Bombardment from over 40 heavy artillery pieces, including lyddite shells and Maxim fire.
- A direct assault by 1,500–2,000 British troops, advancing in a semicircle under cover of fire.
Early on the morning of the 27th, Inspector Kommandant P.R. Oosthuizen and S. Van Lier (ZARPs) occupy trenches dug during the night. From there, the commanders go to the front guard post of the police on the hill. The group sat quietly behind their sconces, ready to take on the British.
Despite suffering heavy losses, van Lier’s detachment held their ground for hours. During the engagement, he was seriously wounded by shrapnel in the thigh and side, and at one point was nearly buried alive when a lyddite shell struck the rocks beside him.
Acts of Bravery
Van Lier’s courage was matched by his men:
- Lieutenant F. Pohlman was killed by a shot to the temple after encouraging his men under fire.
- Sergeant John Pretorius fell mortally wounded, remembered as a young man who often spoke fondly of his bride-to-be.
- Sergeant-Major Biljon risked his life to drag the badly wounded van Lier to safety, ignoring the storm of bullets around them.
Of the 67 Johannesburg Police Corps men, only 31 answered roll call the next day.
Recognition
Though forced to retreat under overwhelming pressure, van Lier and his men received personal commendations from General Louis Botha, General Ben Viljoen, and General Lucas Meyer. Their stand drew admiration even from foreign military observers who were astonished by their discipline and bravery against such odds.
Personal Account
Van Lier later described his experiences in a letter to his father in Amsterdam (November 1900), published in the Dutch press (NRC, 20 November 1900). His words captured both the horror of the bombardment and the unshakable determination of his comrades.

The Johannesburg Police Corps
Shortly before the well-known Battle of Berg-en-Dal on 27 August, this group photograph was taken. In the foreground are seven brave men who, under the name of the Johannesburg Police Corps, became so renowned.
The two articles dedicated to the storming of this same position — worth preserving beyond the fleeting life of a daily newspaper — were written by Commandant of the Volunteer Cavalry with the Johannesburg Police Corps, Mr. S. van Lier (pictured top right). These articles appeared in the Nieuwe Rotterdamsche Courant of 20 November, and re-reading them while viewing this group is deeply moving.
At the top left is P. de la Rey, private; next to him, in order: Commandant Ph.R. Oosthuijsen, wounded and captured; F. Pohlman, First Lieutenant, killed by a shot to the right temple — he who had not seen his dear wife and children for more than a year, he who with Oosthuijsen and Van Lier for almost a year had faced countless dangers shoulder to shoulder, he, the hero of Colenso. Then Van Lier himself, who, with two shots in the right thigh and his side pierced by a shell fragment, incredibly escaped death, and to whom Botha and Viljoen came the morning after the battle to express their great satisfaction for his displayed bravery.
Bottom left: Sergeant John Pretorius, fatally struck in the head, the strong and handsome man who always spoke so lovingly of his bride, whom he had left on the eve of marriage to go to war; Sergeant-Major Biljon, missing, likely killed, after he had saved Van Lier from certain death; Sergeant-Major John Smith, wounded with two bullets in the leg.
At Helvetia, while the roar of cannon still echoed from Machadodorp, where some of General Viljoen’s commandos held back the enemy, roll call was held for the Police Corps. Of the 67, only 31 answered their names.
Neerlandia is not a war journal, but the names and images of these brave men rescue them from oblivion, full of admiration.
