plan, and it offered good promise of success. Now for the execution. [Illustration: IN CAMP: GETTING DINNER READY.] [Illustration: OFFICERS' MESS: PREPARATIONS FOR BREAKFAST.] [Sidenote: Another crossing of the Tugela.] On the 4th the troops began to move. Generals Hart and Hildyard crossed from the British left to the right; General Lyttelton withdrew from One Tree Hill and was replaced by Wynne; in all directions great clouds of dust rose from the rough tracks, indicating to the eyes of the expectant Boers the march of thousands of men. With dawn of the 5th the cavalry struck its camp on the left and also moved off--the squadrons at a walk. Pontoon bridges already spanned the Tugela to the east of Potgieter's Drift, allowing men readily to cross from the neighbourhood of One Tree Hill to the tongue of land enclosed by the river which runs up to Vaal Krantz. Yet another bridge was to be built at Munger's Drift, on the further side of the tongue, to allow the passage of troops from this tongue to the northern bank of the Tugela. The engineers with the pontoon train were ready, waiting to get to their work as soon as the demonstration against Brakfontein fully occupied the attention of the Boers.
