Shortly after the close of the Egyptian War, Mr. Robertson received his commission. He served for some time as junior chaplain in London, and then was removed to Dublin. From Dublin he went to Edinburgh, and remained there until he was ordered to South Africa, as a member of General Wauchope's staff and chaplain to the Highland Brigade. In South Africa he has greatly distinguished himself, and it goes for saying that 'Padre' Robertson, as he is affectionately called, is one of the most honoured and best-loved men in Her Majesty's army.
We will, however, allow the head of the military work in the Presbyterian Church (the Rev. Dr. Marshall) to tell himself of Mr. Robertson's work in South Africa. We quote from an article published by him in the Home and Foreign Mission Record:—
'Of the work of the Rev. J. Robertson in the field, it is unnecessary to write, as the newspaper correspondents have referred so often to his bravery and splendid services. One correspondent writes to me: "It is no exaggeration to say that the whole of Methuen's army, and especially the Highland Brigade, deem his bravery worthy of the V.C. Everywhere, in train or camp, officers' mess or soldiers' tent, Padre Robertson is proclaimed a hero." I was pleased to notice in the Record (the Church of England weekly), the other day, a letter from the Church of England chaplain who is with Lord Methuen. After describing the battle of Magersfontein, he refers to the Highland Brigade: "Being chiefly Highlanders, they were in Robertson's charge. He, good-hearted fellow, was risking his life in the trenches and under fire to find General Wauchope's body. Why he was not killed in his fearless efforts I cannot say." In one of the latest telegrams I see reference to him at the battle of Koodoosberg, whither he had accompanied General Macdonald and the Highland Brigade. "One interesting feature of the fighting was the activity of Chaplain Robertson. He acted in turns as a galloper, as a water-carrier, and as a stretcher-bearer. Wherever a ready hand was wanted, the chaplain was always to the fore, and won golden opinions from officers and men alike."
'You must not, however, suppose Mr. Robertson's exertions are altogether in the field or connected with matters which lie outside his duty as a minister of Christ. While employed by his general as a despatch rider and intermediary with the Boers, and in many other ways in which as "non-combatant" he could be useful to the army, and especially to his own Highlanders, he has given his chief thought and work to their spiritual concerns. We have all noticed his name in connection with the pathetic funeral of his much-loved chief, General Wauchope; but for days after each of the battles of Modder River and Magersfontein he was busy identifying and burying the dead. Being, as a Presbyterian minister, a persona grata to the Boers, he was allowed nearer to their lines than any one else, in the discharge of those sad duties, and conducted many funerals both of Boer and Briton. Speaking of his feelings in the field hospital and alongside the burying trench he says: "War seems devil's work. But all the same, war has its better side, and out of evil has come good. Hearts have been softened. We have frequent meetings of an evening. Hundreds attend. I've never been at heart so touched myself, nor so evangelical. I seem to hear repeated, 'Woe is me if I preach not the Gospel.' I thank God the Gospel at Modder is proving in not a few cases the power of God unto salvation."'
In another letter to a mutual friend, Mr. Robertson speaks of his services on the last Sunday of the year, and as showing how deep is the spiritual impression produced, he wished me to be informed that at the close of the short service he asked all who desired to partake of the Holy Communion to remain. To his joy some 250 officers and men came and took their places at the Lord's Table. To any one who knows how difficult it is to get soldiers to come to the Communion, that fact speaks volumes for the extent and depth of the religious movement among our men. They have had much to make them serious. The death of their beloved General Wauchope and of so many of their comrades must have greatly affected them. Mr. Robertson says, 'There is only one heart in the Highland Brigade, and it is sad and sore. But good is being brought out of evil.'
At the meeting of the General Assembly of the Church of Scotland, held this year, the Moderator said he wished to read the following letter from Scottish soldiers at the front, which had just been put into his hands:—
'WINBURG, May 7th, 1900.
'From the warrant officers, non-commissioned officers, and men of the Highland Brigade, to the Moderator of the General Assembly, Church of Scotland.
'Sir,—We, the undersigned, as representatives of the regiments now forming the Highland Brigade at present serving in South Africa under General Hector Macdonald, do hereby desire to express our appreciation of the untiring energy and praise-worthy zeal of Major J. Robertson, our chaplain, not only in camp, but also on the field. He is invariably among the first to succour our wounded, and many a Scottish mother's heart will be gladdened by the knowledge that her lad's last moments were brightened by our chaplain's kind administrations. At Magersfontein, Paardeberg, and other engagements, he was always to be found in the firing line, with a cheerful word or a kindly nod of encouragement, and on many occasions has acted as A.D.C. to our generals. Sir, soldiers are proverbially bad speakers, but we venture to request that this short note may be read aloud on the occasion of the meeting of the General Assembly at Edinburgh during May, 1900.'
The letter bore twenty-five signatures, including that of the sergeant-major and sergeants and corporals in the Black Watch, the Highland Light Infantry, the Seaforths, and the Argyll and Sutherland Highlanders.
