It's made of packed sand, this line.

You don't blow up sand, you wash it away.

And he proposes to use high-pressure water cannons.

And they've already got these high-pressure equipment at the canal because it's used for drenching operations in the canal.

So they have everything they need already to hand.

And he has this genius idea that he will attach these pumps to floats.

He'll float the pumps in the canal and he'll wash away the sandbank with powerful jets of water and do it instantly.

So they test this.

And to everyone's thrill on the Egyptian side, when they try it out, it works perfectly.

So they quietly import 300 more British-made petrol-driven pumps, 150 more German pumps are added to it with gas turbines.

And each combination of two German pumps or three British pumps can, they estimate, blast through a 15-meter section of wall in under two hours.

And so this fortification that's built to withstand an artillery onslaught can be washed away with jets of water very quickly.

Exactly that.

So they have one other very clever idea, which is to do this on the holiest day of the Jewish year.

Yeah, literally.

So they pick on this time, 2.05 p.m.

And at this point, 2,000 guns, rocket launchers and mortars open up simultaneously.

And the noise is so massive, it's heard in Cairo.

It's 200 miles away.

2,000 artillery pieces firing 10,500 shells in the first minute.
