The Australian Victories in France in 1918

by Sir John Monash

The force of Tanks placed at my disposal for the purposes of this battle comprised the 2nd, 8th and 13th Tank Battalions, commanded respectively by Lieut.-Colonels Bryce, Bingham and Lyon, all under the 5th Tank Brigade, commanded by Brigadier-General Courage. All these Tanks were of the Mark V. type, as used at Hamel; but there were also attached to the same Brigade a Battalion of Mark V. (Star) Tanks, of still later design, under Lieut.-Colonel Ramsay-Fairfax, and also a full Company of 24 Carrying Tanks, under Major Partington. These Carrying Tanks were not employed in fighting, but were of wonderful utility in the rapid transport of stores of all descriptions across the battle zone; and in carrying the wounded out of the battle on their return journey. I am confident that each of these Tanks was capable of doing the work of at least 200 men, with an almost complete immunity from casualty.

There were thus available to me 168 Tanks in all, and their dispositions have been already indicated in sufficient detail in Chapter V. It was a definite feature of the whole plan of battle that the combined Tank and Infantry tactics which had proved so successful in the Hamel operation, and which have been described in Chapter II., were to be employed and exploited to their utmost. Each Tank became thereby definitely associated with a specified body of Infantry, and acted during the actual battle under the immediate orders of the Commander of that body: the working rule was "one Tank, one Company."

To this was added the second working principle of "one Tank, one task," which rules meant, in their practical application, that no individual Tank was to be relied upon to serve more than one body of Infantry, nor to carry out more than one phase of the battle. Elementary as this may sound, it involved this striking advantage that, in the event of any one Tank becoming disabled, its loss would impair no portion of the battle plan other than that fraction of it to which that Tank had been allotted.

Thus, the whole of the Infantry operating in Phases B and C of the battle had each their own adequate equipment of Tanks, which would be certain to be available to them, even if the whole of the Tanks employed during Phase A had been knocked out. At the same time clear orders were issued, and due arrangements were made, that all Tanks which survived Phase A, and whose crews were not by then too exhausted, were to rally (during the 100 minutes' pause on the green line) in order to co-operate in the succeeding phases of the fight.

There was still another Unit, coming under the jurisdiction of the Tank Corps, which proved of wonderful utility to me, and which deserved quite special mention. This was the 17th Armoured Car Battalion, organized into two companies of eight cars each. Each car carried one forward and one rear Hotchkiss gun. It was heavily armoured, and the crew operating the guns, as also the car driver, were protected from all except direct hits by Artillery. The cars had a speed of 20 miles per hour, either forwards or backwards. The Battalion was under the command of Lieut.-Colonel E. J. Carter, an officer of the British Cavalry. I allotted 12 cars to the use of the 5th Australian Division, under Major-General Hobbs, who would be likely to find specially useful employment for them, in scouring the network of roads beyond his final objective; and retained four cars in Corps reserve for a special reconnaissance enterprise.

Full of promise of usefulness as were the speed and armament of these cars, they suffered from one serious disability. Their top hamper was so heavy compared to their light chassis that they could not be relied upon to travel without premature breakdown across country, or indeed on anything but moderately good roads. Now, such roads were certainly available, as was evident from aeroplane photographs, in the enemy's back country, after a zone for a mile or two immediately behind his front line was passed; but all the subsidiary roads in that zone had been practically obliterated by shell-craters, and even the great main road from Villers-Bretonneux to Saint Quentin, which is a Roman Road and substantially constructed throughout, was known to have been cut up and traversed by numerous trenches both on our side and on the enemy's side of "No Man's Land." There was also every expectation that the few remaining trees which flanked this great road would be felled by our bombardment, and some of them would surely fall across and obstruct the roadway.

That road was, however, the only possible outlet into enemy country for the armoured cars, and I resolved upon a special programme, and the allotment of a special body of troops for its execution. The object was to ensure that the cars could be taken across the impracticable and obstructed stretch of roadway already described, and launched at the enemy at its eastern extremity, at the earliest possible moment of time. Then, before the numerous enemy Corps and Divisional Headquarters and all their rear organization had time to get clear intelligence of what was happening at the front, or to recover from the first shock of surprise, these Armoured Cars would fall upon them, and, travelling hither and thither at great speed, would spread death, destruction and confusion in all directions.

A whole Battalion of Pioneers, and detachments of other technical troops, with an adequate amount of road-repairing material, were got ready, under the direct orders of my Chief Engineer, to carry out this special task. All trenches in that portion of the road lying within our own zone of occupation were bridged or filled in and all obstructions cleared away before the day of the battle. But as to the more distant stretch of the road, still in the hands of the enemy, elaborate preparations were made, by a careful and detailed distribution of tasks to small gangs of men, and by a fully worked-out time-table. The plan was that from the moment of the opening of the battle, this road repair work was to commence, and its advance was to synchronize with the advance of the Artillery barrage and Infantry skirmishing line.

A pilot armoured car was to follow the working gangs in order to test the sufficiency of the repair work, and arrangements were made for sending back signals to the remainder of the cars, lying waiting in readiness in the shelter of Villers-Bretonneux. It was planned that the first two miles of road would, by these means, be cleared and repaired to a sufficient width, within four hours after the opening of the battle.
