Mafeking, being a railway junction, provided good supply facilities and was the obvious place for Baden-Powell to fortify in readiness for such attacks. However, instead of being the aggressor Baden-Powell and Mafeking were forced to defend when 6,000 Boer, commanded by Piet Cronjé, attempted a determined assault on the town.
