Al Murray: Yeah, and it was no easy ride—mines, U-boats, coastal batteries, rough seas, and a load of Germans who really didn’t fancy the idea of surrender. But what do the Allies do? They put together a flotilla like nothing the world had ever seen—battleships, cruisers, destroyers, landing craft, and even floating harbours. The Royal Navy, the US Navy, the Canadians—everyone was in on this. And it worked.
James Holland: Absolutely. The naval bombardment alone was staggering—guns from HMS Warspite, USS Texas, and countless others hammering the beaches, clearing the way for the landings. But Neptune wasn’t just about firepower—it was about coordination. Thousands of ships, millions of tons of equipment, and an entire army hitting the beaches at once. This T-shirt? It’s a tribute to the sheer scale and strategy of Operation Neptune—the moment the Allied fleets ruled the waves and delivered the knockout blow in Normandy.

A Bit About the T-Shirt (And Why You Should Check Your Size!)
Al Murray: Now, let’s talk about the T-shirt itself—this isn’t some cheap knockoff; it’s print-on-demand, which means no wasted stock sitting in a warehouse somewhere gathering dust. Instead, every shirt is printed just for you, which is a win for both history lovers and the planet.
James Holland: Absolutely. But, and this is important—check your size before you order. We don’t want loads of returns bouncing around, adding to unnecessary emissions. Pick the right fit, wear it with pride, and show the world you know your history.
This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!

Nice shirt, good quality. No notes.

An excellent T shirt - love the relevance of the Codenames - it makes it special. Lots of folks have asked what it means - it’s educating people!

Beautiful quality tee in a fabulous fabric. Given the item is individually printed the delivery time was swift and the delivery company efficient.
Thanks for the comprehensive size guide, the tee is also a perfect fit.
I look forward to buying more kit from WW2 Headquarters very soon.

The T-shirt is great quality. The sizing is accurate so just order the size you usually order without worry. Considering these items are made to order, the delivery time was also quicker than expected. I'll be ordering again, for sure.

Everything is too like great quality

Really good

Good quality, heavy cotton. Nice colour etc.
Just be worried if someone brings me a Piat when I’m out and about wearing it. It’s just a saying today.

A quality T-Shirt with great logo, will be wearing this a lot this summer.

Good quality product with fun graphics but at £16 for one mug overpriced.

Great! Arrived well packaged and the artwork on the mug looks fantastic
