I am neither an architect nor an Engineer by trade. I am a natural tinkerer and have spent most of my life breaking my toys, so I have an appreciation for how things are made and what it takes to make them. As such, I spend a lot of time noticing differences in construction: things like the pathetic stitching on the snaps of Hasbro’s G.I. Joe camouflage fatigues the last year they were made. Incidentally, I still have a set of those cammies from their first year of production. Bombproof!
This is all a way of saying that newer isn’t necessarily better. Last week I was watching a re-run of a World War Two documentary in which Germany invaded France by running around the Maginot line. While discussing river crossings and their importance to military operations, historic film reels were played showing a German tank crossing a makeshift bridge; one hastily constructed from little more than timbers laid across numerous small boats. This bridge struck me as familiar and I began to sift through my library for references to this construction as it seemed out of place in this German war footage.

I worked backwards in time and was consulting J. Caesar’s The Gallic War without finding my bridge, so I looked further back in time. Finally, I found it. The description went something like this:
Many boats (654) were placed side-by-side and facing into the current while cables were used to secure them to the shore and the individual bows were anchored up and down stream to keep the boats in line relative to each other and adding more stability. Boards were then placed between the boats and over the cables to connect them while brushwood and soil were placed over the boards to create a walkway and a more even surface after which a handrail was placed on either side to keep soldiers and beasts of burden from falling in.

This resource that listed my bridge was actually Herodotus when his Histories were describing how the Persian Empire invaded Greece. Xerxes used this bridge type to cross the Hellespont in 482BC (circa). This narrows is approximately 1240 metres (1350 yards) of the most difficult waters in the world. This successful iteration was actually the second effort. The first had ended badly for all: the engineering supervisors were beheaded and the waters of the Hellespont were flogged with 300 lashes while being subjected to verbal abuse for being disobedient.

So, in 2019 I saw a film from 1939 which spoke about how technologically advanced the German Army was and how incorporating this technology gave the Germans a battlefield advantage. Yet in this film, our twentieth century technological genius’ used a bridging technique from 2,421 years earlier. Perhaps part of their genius was their ability to recognise when something works well.
