Viewing the Past with the Technology of the Future

How satellite and aerial photography brings the war diaries to life

by Cynthia Gast

Most people, and especially the volunteers working on Operation War Diary, will recognize the names of the locations that played the biggest roles in World War I. Cities such as Ypres and Passchendaele along with regions such as the Somme were the sites of horrific fighting. Poperinghe was known to the soldiers as a place where they could have a break behind the lines, and the unfortunate mademoiselle from Armentieres is immortalized in song.

There are countless other towns, villages, farms, and forests that appear in the diaries. Each one is a place where the men of that unit fought, marched, or slept. To me, an important part of the story of the men on the Western Front is where they were. Where did they spend Christmas? What did they see in the villages behind the lines where they spent their rest periods? Where was that hill that caused so much trouble for the transport on a dark rainy night? I’ve spent a lot of hours searching for some of these locations.

Google Maps

The first step, even before filling in the Place tag, is to search for the name on Google Maps. I’ve learned that not all diary authors had a good grasp of the intricacies of spelling French place names and the search function in Google Maps helps with this problem by supplying several suggestions before I’ve even finished typing in the entire name.

Google Maps has a couple of other helpful features as well. I’ve learned that clicking on the town’s name on the map puts that name in the tab at the top of my browser. This is quite handy for spelling when I return to the diary page to type it into the Place tag. Another interesting detail is that while many of the very tiny hamlets are not labeled on the basic Google map, they do show up on the Google Earth view. An example of this that I came across recently involved the 1 st Division Trench Mortar Batteries. Their diary said they were in the village of Berthaucourt and I knew they were somewhere near Saint-Quentin. A search on Google Maps told me that Berthaucourt is now part of Pontru, but no matter how closely I zoomed in, there was no indication of its exact location. However, when I switched the view to Google Earth, I learned that it is just to the east of the crossroads that form the heart of Pontru.

Farms

As I’ve moved through the diaries, I’m less content with locating just the villages and towns mentioned by the author. These days, I’m digging deeper and looking for the farms and chateaus used as billets and bivouacs. I’m amazed at how many of the farms mentioned in the war diaries are still in existence today.

When I want to find a farm, I start on Google Maps, where search results are more likely to show me a road rather than the farm itself. However, when I zoom in on Google Earth view there’s often a cluster of farm buildings along that road. Sometimes I hunt using Google’s basic search function, which is particularly useful for chateaus.

Trench Maps

Many World War I trench maps are now available online. Some sites offer sets for purchase but, along with IWM’s map collection, there are at least two sites that allow users to examine them at no charge. The National Library of Scotland and McMaster University in Canada both offer collections covering the areas where most of the fighting occurred. They both also offer information and links that cover how to read the maps, including the grid references. As an added plus, McMaster University also has a collection of aerial photographs of the Western Front.

Trench maps are fascinating. They reveal the complexity of the trench systems and show just how the features of the landscape fit into the systems. They also show the sometimes dark sense of humor possessed by the men who named the trenches. Whole sections of trenches are named for weapons, animals, or birds, as well as places back home, commanding officers, and the units occupying them. One system near Delville Wood featured trench names relating to beer, such as Pint Trench, Hop Alley, Ale Alley, Beer Trench, and Lager Lane.

Trench maps also often include farms, chateaus, villages, and anything else of importance to the men in that area, such as quarries and brickstacks. They also indicate the roads existing at the time the maps were drawn, many of which still exist today. When I want to find a farm or chateau, I compare the trench map with the modern map or Google Earth view using the roads as a guide. The National Library of Scotland also offers side-by-side and overlay features to help compare the old and present-day maps.

When I began as a volunteer at OWD, I had no idea of the things I would learn. The geography of the Western Front and how to read trench maps are just two of the amazing aspects of World War I that I now know. There are still many diaries to read and men to get to know through the official diaries they kept, and lots of spaces for more volunteers.
