It is probable that all these demonstrations of the enemy upon the right of Lord Roberts's extended position were really feints in order to cover the far-reaching plans which Botha had in his mind. The disposition of the Boer forces at this time appears to have been as follows: Botha with his army occupied a position along Delagoa railway line, further east than Diamond Hill, whence he detached the bodies which attacked Hutton upon the extreme right of the British position to the south-east of Pretoria. To the north of Pretoria a second force was acting under Grobler, while a third under De la Rey had been despatched secretly across to the left wing of the British, north-west of Pretoria. While Botha engaged the attention of Lord Roberts by energetic demonstrations on his right, Grobler and De la Rey were to make a sudden attack upon his centre and his left, each point being twelve or fifteen miles from the other. It was well devised and very well carried out; but the inherent defect of it was that, when subdivided in this way, the Boer force was no longer strong enough to gain more than a mere success of outposts.
