Charley's War is the equivalent in comic to "All Quiet on the Western Front", it should be a recquired reading in British schools.
Volume 2 just came out this year, though it's uneven in quality, the storyline moves between the superb and the weak conventional gung ho heroics of action comics. What is unforgivable is that with so great attention to detail and historical accuracy, the first episode where we see airplanes in the series is an air raid by Albatros DV (or DVa, it depends of wether the artist remembered to draw the aileron control cables or not) fighters countered by Sopwith Camels...in August 1916!
Don't get me wrong, the planes are superbly drawn, and the episode is good in showing what's an air raid like, but it seems that the writer lost it's sense of direction or had editorial pressures because the strip had not enough action and it seems like a hasty concocted filler. But don't be put off, the human interest story is gripping, and the main story arc covering the first employ of tanks in battle is exceptional. The book closes with a trench raid by German storm troops, wich in the basics being researched, it's more comicbook style that historically accurate, an again would have been more properly placed in 1917 than in 1916.
Despite these continuity blunders, I highly recommend it. I read a lot of Charley's War reprints in a random order when I was in England one summer learning english when I was a youngster , and can't wait for the next volumes, that will eventually cover Passchendaele (3rd Ypres) and the Etaples mutiny. I credit Charley's War with sparking my interest in World War I.
