Battalions had been reinforced since the Gommecourt action, and there was some grumbling about the nature of the reinforcements. Batches of men, from all sorts of units, were drafted to battalions, and General Hull made great efforts to get this system altered. Battalions, however, were of fair strength.

We know that very early in the war the problem of barbed wire had been exercising the minds of the Staff in general. Long after the Press campaign for high explosives, when this form of shell was provided in large quantities, wire-cutting was still ordered with quite a high percentage of shrapnel. But whatever you did, however long the time you gave to cutting the wire, it never disappeared entirely; vile, treacherous strands stuck out of the earth like brambles, stakes remained miraculously upright with waving lengths of wire to grab you by the sleeve or the trousers; and when the cutting was well done, there had been a mere substitution of obstacles—the state of the ground, blasted into holes, pits, mounds, and mud made progress very slow and difficult.

How was wire to be removed?

Mr. Winston Churchill let his mind wander round steam-rollers linked up with chains. Other minds thought of tractors. At the same time, inventors were considering the old question of moving forts.

In August 1916 there came from England a weird and fearful-looking machine known as a Tank.

On the 26th August the 7th Middlesex practised an attack in conjunction with five Tanks. One can easily imagine the Middlesex men, and everybody else who had wind of what was afoot, all agog at this new form of field training! What were the criticisms of the London men on this ... machine?

The Tanks had only been landed in France on the 25th, and it is not surprising that two of them broke down. But the practice was continued on subsequent days until each brigade had acquired experience. Sir Douglas Haig, Marshal Joffre, and H.R.H. the Prince of Wales were interested spectators of these evolutions.

The orders for this exercise were that the Tanks would cross our front line at zero hour, and would be followed by the first infantry wave one minute later. The second wave would start at zero plus three minutes; the third wave at zero plus five minutes; the fourth wave at zero plus six minutes. The infantry were instructed to advance in short rushes up to, but not beyond, the Tanks—unless a Tank broke down, when they were to proceed as if it was not there.

Everyone seems to have been much impressed by the behaviour of the Tanks.

On the 31st August, General Hull received a warning order that his division would move to Corbie and come under the XIV Corps (Cavan). And on the following day the artillery was ordered forward. The 168th and 169th Infantry Brigades left St. Riquier on the 3rd, and the 167th Brigade on the 4th. Events came tumbling over one another.
